Hey there, I’m Jonathan, a 17 y/o privacy nerd + coder, and I’ve been building a project the last month called Oxidiko — a serverless, privacy-first login/authentication system designed to minimize your attack surface and stop the usual password leaks we’re all sick of hearing about. It's like a mix of Bitwarden and OAuth2, with no password managment hell and more privacy. You know how: every site asks for your email & password (then leaks them 🙃) auth flows are centralized & you’re just trusting them with your identity and the more accounts you have, the bigger your risk footprint becomes Yeah. That sucks. 🔑 Why I made it I wanted something secure, serverless, and portable, without handing over my info to yet another company. Something that lets me decide what data (if any) to share, and minimizes what attackers can even steal in the first place. 🧩 What does it solve? ✅ No passwords to leak — users get an oxidiko_id derived from a passkey and a fallback PIN. Websites can just verify the signed JWT with my public key, and done. No secrets flying around. 🚀 What’s next? After I get back from a 10-day vacation, I’ll be working on a feature that lets users fully self-host Oxidiko. 📬 I’d love to hear what you all think! Any feedback on the concept? Ideas for making it even more secure or easier to use? Do you see yourself trusting something like this? Why/why not? I’m open to roasting & suggestions — you’re the perfect audience to poke holes in it.

Kafka Lag Monitoring: A Deep Dive for Production Systems 1. Introduction Imagine a financial trading platform where real-time price updates are critical. A delay of even milliseconds can lead to significant financial losses. This platform relies on Kafka to ingest market data from multiple exchanges and distribute it to downstream trading algorithms. A key indicator of system health isn’t just Kafka’s overall availability, but the lag between data production and consumption. If consumers fall behind, trades can be executed based on stale data, creating arbitrage opportunities for competitors or, worse, regulatory violations. Kafka lag monitoring isn’t simply about alerting on a number; it’s a fundamental component of building reliable, real-time data platforms. It’s interwo…  ( 7 min )

The main difference between Dapper and Entity Framework Core (EF Core) lies in their approach, performance, and level of abstraction in working with databases in .NET applications. Here's a detailed comparison: Dapper vs Entity Framework Core Feature Dapper Entity Framework Core Type Micro ORM (Object-Relational Mapper) Full-fledged ORM Performance Faster – Almost as fast as raw ADO.NET Slower compared to Dapper (due to abstraction) Ease of Use Manual SQL writing required Query generation handled automatically Learning Curve Easier for SQL-savvy developers Steeper (especially for advanced features) Query Language Raw SQL LINQ Control Over SQL Full control Limited unless using raw SQL or FromSqlRaw Change Tracking ❌ No automatic change tracking ✅ Yes Caching ❌ No built-in caching ✅ First-level caching supported Lazy Loading ❌ Not supported by default ✅ Supported Migrations Support ❌ No migrations ✅ Built-in migrations Best Use Case High-performance, read-heavy applications Applications with complex data models and CRUD Complex Joins Manual (you write the JOIN) Handled via navigation properties and LINQ Setup Complexity Lightweight and simple Requires more setup and configuration When to Use Dapper: You need maximum performance (e.g., reporting, high-traffic APIs). You prefer writing raw SQL yourself. Your app is read-heavy or has simple CRUD operations. You want a lightweight ORM. When to Use EF Core: You want rapid development with less manual SQL. Your application has a complex domain model. You need automated change tracking, migrations, and relationship management. You prefer LINQ queries over SQL. var user = connection.QueryFirstOrDefault("SELECT * FROM Users WHERE Id = @Id", new { Id = userId }); var user = dbContext.Users.FirstOrDefault(u => u.Id == userId); Happy Coding!  ( 3 min )

What if you could approach any database and its query language was just syntax? The trick isn’t more SQL, it’s relational algebra (RA): the intent layer driving every query. Don’t worry, no scary math here. We’ll use plain JavaScript to break down joins, groups, differences, and more. RA is your mental toolbox to reason about any SQL query before writing a single line of code. Once RA clicked for me, I could scan any DB, SQL, NoSQL, graph, and instantly “get” it. Ever messed up a deep-dive database analysis at work? (guilty.) This’ll let you boss your next one. The language of intent. Its one job? Express intent clearly.

Classes were likely the first thing Stroustrup added in the 1980s, marking the birth of C++. If we imagine ourselves as archaeologists studying ancient C++, one piece of indirect evidence supporting the theory would be the 'this' keyword, which is still a pointer in C++, suggesting it was introduced before references! We published and translated this article with the copyright holder's permission. The author is Kelbon. That's not the point, though. Let's look back at C++'s evolution since then: the language and its paradigms development, the natural selection of best practices, and occasional "significant discoveries".

Technical Due Diligence (TDD) is a thorough evaluation of a company’s technology landscape. It encompasses a deep dive into the products, technical infrastructure, architecture, product roadmap, services, operational practices, and IT talent. TDD is typically performed prior to major corporate milestones, such as mergers and acquisitions (M&A) or initial public offerings (IPOs). While investors most often initiate TDD, companies themselves may proactively conduct it to prepare for future funding rounds or investments. The assessment can be carried out by either internal teams or specialized third-party agencies. Why is Technical Due Diligence Essential? TDD provides critical insights before making a commitment.

If you know how to build a gaming PC, you're already halfway to understanding how to run an ASIC Miner. From power supply theory to firmware tweaks, this guide breaks down why your PC skills transfer directly into the world of crypto mining. If you've ever built a PC, you already understand the fundamentals of operating an ASIC Miner. You've managed airflow. You've undervolted a GPU. You've flashed a BIOS or two (and maybe bricked one). An ASIC (Application-Specific Integrated Circuit) miner isn’t some black box — it’s a performance-optimized, single-tasking machine. It doesn’t run games or render videos. It hashes. That’s it. But in the same way your PC needs proper thermals, power, and monitoring — so does your ASIC. Remember dialing in the perfect GPU overclock for max FPS? Same energy…  ( 4 min )

As a developer, I've spent way too much time writing throwaway SQL queries just to answer simple questions: "What’s in this table again?" "How many users signed up last week?" "What foreign key links these two tables?" There are some great database tools out there, but many of them feel either bloated, overly complex, or too cloud-focused for simple day-to-day work. So I built something that fits how I want to work with databases. Data Ramen is a lightweight, local-first GUI for exploring your PostgreSQL and MySQL databases. Connect to a local or remote DB (PostgreSQL or MySQL) Browse tables, columns, and relationships without SQL. Contrary to many SQL editors, connection works both ways, not only from the table which contains the foreign key Filter, sort, and join data through a point-and-click interface Insert and edit rows in-place Drop into raw SQL whenever you want It’s built to be fast, focused, and doesn’t try to replace your existing tools, just makes common DB tasks a lot easier. Data Ramen is still in beta, but you can try it today: npm install -g @dataramen/cli dataramen start Then open your browser at: app.dataramen.xyz. Runs entirely on your machine (local-first). For more info, visit home page at dataramen.xyz. This is still early. I’m testing ideas and figuring out what’s most useful. If you’re working with SQL databases and want to try a different kind of GUI, I’d love for you to check it out. Questions, bugs, thoughts, or "this is useless because X"?

That’s what the color-mix() function does, but unlike a real-life palette that allows you to merge any amount of different paints, the function is restricted to only two colors in a selected color space. .color-1 { background-color: red; } .color-2 { background-color: blue; } .result { background-color: color-mix(in srgb, red 50%, blue 50%) } The color-mix() function is defined in the CSS Color Module Level 5 specification. The syntax for the color-mix() function is defined below: color-mix() = color-mix( , [ && <p…  ( 8 min )

I’ve always thought of myself as an inclusive designer, but during Asurion’s A11y Maven Cohort 2 training, I started to realize there’s still more I need to learn and more I could be doing. While attending Axe-Con virtually this year, two talks stood out to me. One approached accessibility from a philosophical angle, and the other from a practical viewpoint. Together, they reframed how I’m thinking about inclusion and raised a question I keep coming back to: Who do we actually mean when we say “human” in human-centered design? This question, along with A11y accessibility training, pushed me to reflect on my own background and on the many winding paths that lead people into product design. What we don’t talk about when we talk about the path to product design One of the things I love mos…  ( 8 min )

Rust is often hailed as a modern systems programming language that serves as an attractive alternative to C++ for developers, particularly those who are less experienced or more prone to making mistakes. Its appeal stems from its compiler and runtime features, which prioritize safety, clarity, and usability while delivering performance on par with C++. Below, I’ll dive into why Rust’s compiler and runtime stand out for such developers compared to C++, focusing on aspects that reduce errors and simplify development. Rust’s Compiler: A Safety Net for Beginners Rust’s compiler is renowned for its strictness and helpfulness, acting as a guide that catches potential issues early in the development process. This is especially valuable for less experienced developers who might not yet have a de…  ( 8 min )

Streamlining Data Access with Google Cloud Digital Asset Links API The modern data landscape is complex. Organizations are grappling with increasing volumes of data, distributed across multiple cloud providers and on-premises systems. This fragmentation creates challenges for data scientists, engineers, and analysts who need secure, efficient access to these assets. Consider a financial institution needing to train a fraud detection model using transaction data residing in both GCP and AWS. Traditionally, this would involve complex data pipelines, significant data duplication, and potential security vulnerabilities. Furthermore, the growing emphasis on sustainability demands minimizing data movement and processing overhead. Companies like Spotify leverage similar architectures, needing…  ( 9 min )

Tell us about yourself and how many books you have written.

Asynchronous I/O (Input/Output) is a programming paradigm that allows a program to continue executing other tasks while waiting for I/O operations, such as writing data to disk, to complete. This approach can significantly improve the speed and efficiency of applications that frequently write data to disk, especially in environments with high I/O demand. Below, I'll explain how asynchronous I/O boosts performance and highlight potential pitfalls to watch out for. How Asynchronous I/O Improves Speed Non-Blocking Operations: In traditional synchronous I/O, a program halts execution (blocks) until the I/O operation (e.g., writing to disk) is complete. This can create bottlenecks, especially for disk operations which are inherently slower compared to CPU or memory operations (disk I/O can …  ( 6 min )

Introduction I just started learning and practicing Kamal. While I found it's a joy to finally be able to deploy Docker images on my own machine, there are some challenges. One of the biggest challenges is that it's unreasonably difficult to run cron jobs 🥲 On top of that, I like to use the whenever gem to manage cron jobs, which makes it even harder. I came across a helpful blog post by Alan Morales, which already solves this issue. However, after some research and experiments, I came up with a simpler version, and I'd like to share it here. We know cron is the program that runs routine jobs—like running a script every 5 minutes. cronjobs just means the jobs that will be run by cron. crontab is the command used to edit the cronjobs. (I guess crontab stands for cron table, but I don't h…  ( 5 min )

What I Worked On Today Here’s a quick rundown of the improvements and bug fixes I tackled today in my Next.js project: Link Nesting Error Fix I fixed a common Next.js error caused by wrapping an tag inside a component. This triggers a nesting warning like: "Warning: cannot appear as a descendant of ..." Solution: Removed the inner and applied styling/behavior directly on the component. Button Variant Unification with shadcn/ui To make button styling consistent and easier to maintain, I centralized button variants: variants: { variant: { default: 'bg-primary text-primary-foreground hover:bg-primary/90', outline: 'border border-input hover:bg-accent hover:text-accent-foreground rounded-md', line: 'text-gray-600 hover:text-green-600 transition-colors', cta: 'bg-green-600 text-white hover:bg-green-700 shadow-lg hover:shadow-xl', ghost: 'bg-transparent hover:bg-gray-100 text-gray-700', faqToggle: 'w-full px-6 py-4 text-left flex justify-between items-center hover:bg-gray-50 transition-colors shadow-none hover:shadow-none rounded-md', } } Now buttons across the site are easier to update and visually consistent. Applied Scroll-Based Animations This makes image sections feel more dynamic and engaging.

Today, information is available anywhere, anytime. Millions of websites, endless social media feeds, constant notifications, and streams of messages create an environment where the brain is constantly overloaded. Instead of facilitating access to knowledge, technology is increasingly becoming a source of cognitive overload, making it difficult to focus, analyze, and think deeply about information. Neuroscience shows that our brains are not designed to process large amounts of disparate information at once.

Hey Devs 👋 I just built a small tool called Solana Token Launchpad — a lightweight frontend + backend app to help you create your own SPL Token using the new Token-2022 extensions. You can: Enter token name, symbol, image URL, and supply Upload metadata Deploy your token mint with on-chain metadata Mint tokens directly to your wallet React + TailwindCSS Solana Wallet Adapter Express.js + MongoDB for dynamic metadata URI I struggled a bit with dynamic metadata URIs — since Solana expects a metadata URL, and each token needs a unique one. To solve it, I: Created a simple MongoDB backend to store name/symbol/image Used the generated Mongo _id to construct dynamic metadata URLs like: https://myapi.com/metadata/ This endpoint returns the full metadata JSON Solana needs to initialize the token. Input your token details and launch instantly on devnet. 🔗 Live: Here https://github.com/1rishuraj/TokenLauncher If you're building on Solana, would love feedback, suggestions, or ideas to improve this 🙌 Thanks for reading & happy hacking! 🧙‍♂️  ( 3 min )

The average person pays for 12+ subscription services, spending $273/month according to recent studies according to the new source of truth delivered by your favorite socially awkward CEO, Sam Altman. As a developer, I realized I was paying for solutions I could build myself, starting with a $5/month task manager that does what a WhatsApp bot could do for (sort of) free. So okay, as a first (content) post here, I thought a good idea would be to do something completely unrelated with computer vision, just because.

My journey into web development has been a bumpy road, to say the least. In my naive, delusional brain, I earned my associate’s degree and started applying to jobs. After months of getting zero traction with my resume, I noticed a common thread across most developer roles: almost all of them required a bachelor's degree in computer science or a related field. So, back to school I went. The entire time, I was building projects in my free time, active in Discord servers, and soaking up everything I could about becoming a better developer. I finished a coding program, Code:You, a program in my city and was in college at the same time 😬 (This was rough, but worth it). When I finally graduated, I was full of energy and momentum—I couldn’t imagine any team not wanting to work with me. Now it’s 2025. I’ve got a bachelor’s degree, solid coding skills, mentoring for Code:You, and the will of a warrior ready to go to battle on any codebase. There’s just one problem: AI has reshaped the industry, and the job market is intimidating for new developers. I’ve spoken with every career coach and developer I know. I’ve submitted so many resumes that my head is spinning. At one point, I got desperate—ready to throw away my dream of becoming a developer or tech professional. So I posted on LinkedIn, X, and Facebook, offering freelance work—designing webpages or doing anything tech-related. BOOM! I got a hit. And ever since, I’ve been doing odd jobs here and there for nonprofits, for-profits, and companies around my city. I'm not where I want to be yet, but I am slowly getting there and haven't given up on my dream. The key to this story? Never give up. Network with everyone you can, and make sure people know you’re available—because no one can read your mind. Keep posting your work on social media. Join communities like Code Connector or Discord servers like traversmedia’s (Brad Traversy's)—the advice I’ve gotten from these groups has been invaluable and has kept me moving forward. Thank you for reading, and Happy Coding!  ( 4 min )

When I say "agile and accessibility," some developers may pause. Have you ever heard a story about a developer delivering a product and later discovering that it has major accessibility issues? Cue the firestorm of bug fixes at the last second. There are numerous myths and negative stereotypes surrounding the implementation of accessibility in software projects. This negative connotation can stem from an issue with the agile process. If your team doesn't prioritize accessibility from the start, fitting it into your agile workflow later can feel painful, inefficient, and worst of all: SLOW. What if I told you that I learned how to change that?

Like many others, I recently took it upon myself to complete Forrest Brazeal’s cloud resume challenge: https://cloudresumechallenge.dev/docs/the-challenge/aws/. As someone who already had an AWS Solutions Architect Associate certification and worked on production cloud environments, I wanted to prove my skills and turn my personal website into something more complex. I was also excited because I get to own this project in its entirety, which can be rare in a corporate setting where I may only get to touch Lambdas or S3. While it took months of chipping away before life and its distractions allowed me to finish, I always had it in the back of my mind. It just felt wrong to me to leave this project incomplete. The end result is deceptively complex, with a very basic looking web page that has a lot going on under the hood. Having been scared to try out Terraform, I was pleasantly surprised at how simple it actually was to convert my infrastructure into code and automate any changes into AWS. The tutorials and documentation produced by HashiCorp, along with other users' blog posts made this my favorite chunk. As far as extras, I did take it upon myself to enable DNSSEC, and triple checked that no AWS credentials were committed to code! Also, billing alerts are one of the most useful features in AWS as far as I'm concerned. Really though, I just liked tinkering with all the techs that I came across and refreshing my memory on AWS services. I love having an easily accessible project that I made online and automation to make any changes easily deployed with tests to ensure it works. I'd encourage anyone with an interest in coding or web apps to give it a shot! My site can be found here: https://kyle-miller.net  ( 3 min )

We just released our 2025 State of Engineering Management report for the sixth year in a row. This year’s findings, based on responses from more than 600 engineering professionals, are more eye-opening than ever. According to the report, 90% of engineering teams are now using AI in their workflows, up from 61% just one year ago. Almost a third of respondents have formally supported and widely adopted AI tools, while another 39% are actively experimenting with them. Only 3% of respondents reported no AI usage and no plans to change that. 48% of respondents reported using two or more AI coding tools, suggesting teams are taking a diversified, exploratory approach by evaluating multiple solutions simultaneously rather than standardizing on a single platform. The leader among AI coding tools was Copilot with 42% of surveyed engineers naming it their tool of choice, followed by Gemini, Amazon Q and Cursor.

When your app goes viral and thousands of users start flooding in, you lean on Node.js for its speed and efficiency. You’ve heard about its non-blocking I/O and event-driven core, but few stop to think about how it manages CPU-heavy work when traffic surges. What happens when the event loop meets a wall of complex calculations and millions of open connections—can it keep up without breaking a sweat? It turns out Node.js isn’t just fast; it offers a toolbox of strategies to stay responsive under heavy load. By mastering its event loop, leveraging clustering, and offloading work to separate threads or services, you can design systems that scale to millions of users. Understanding these patterns helps you avoid bottlenecks, make smart architectural choices, and deliver a smooth user experienc…  ( 6 min )

Developers love how Node.js powers scalable servers with non-blocking I/O while JavaScript itself runs on a single thread. Yet most guides breeze past the heart of this magic: the event loop and its off-loading engines. Have you ever paused to ask how Node.js can juggle thousands of connections without spawning dozens of JS threads? It all comes down to libuv’s thread pool and the event loop working in concert. Understanding this interplay helps you spot performance bottlenecks, choose the right patterns, and avoid surprise freezes. Let’s dive in and see exactly how Node.js stays asynchronous on a single-threaded engine. At its core, the event loop is a cycle that picks up tasks and dispatches them to the correct handler without blocking the main thread. Each loop iteration goes through ph…  ( 5 min )

Introduction JavaScript is everywhere in modern web development, powering everything from small widgets to large-scale applications. Yet its typing system often trips up newcomers and veterans alike, leading to unexpected behavior, subtle bugs, and endless debates. One frequently overlooked aspect is type coercion—how JavaScript silently converts values between types under the hood. Have you ever wondered why [] + [] yields an empty string or how == can produce true when comparing wildly different values? The answer lies in understanding JavaScript’s dynamic type system and its rules for coercion. By exploring how and why the language handles types at runtime, you’ll gain clarity, write more predictable code, and prevent those “it works on my machine” surprises. Strap in as we compare dy…  ( 6 min )

Effective error handling is key to building robust applications. By anticipating potential failures and responding gracefully, you can avoid unexpected crashes and provide a smoother user experience. Whether you’re catching synchronous exceptions or managing asynchronous failures, following best practices will keep your code clean, maintainable, and predictable. In this guide, we’ll explore patterns and tips for handling errors in JavaScript—covering everything from try/catch blocks and custom error types to Promises, async/await, and centralized logging. JavaScript has several built-in error classes like Error, TypeError, ReferenceError, and more. You can also create custom error types by extending the base Error class: class ValidationError extends Error { constructor(message) { su…  ( 5 min )

Let's say your team is growing, and more development, staging, and production environments are being launched. At some point, you might hit limits when pulling images from public repositories. It happens, right? That's where ECR Pull-Through Cache comes in to solve the issue. When building containerized applications, developers often rely on public Docker images like nginx, node, or python. These images are pulled from public registries such as Docker Hub. But pulling from external registries comes with challenges; rate limits, availability, and slower downloads sometimes. That’s where AWS ECR Pull-Through Cache comes in. What is Pull-Through Cache? Benefits of Using Pull-Through Cache 🚀 Faster Image Downloads 🔐 Increased Reliability 🛡️ Security & Governance 📊 Reduced External Dependencies 💰 Cost-Efficient CI/CD How It Works (In Simple Terms) AWS ECR creates a mirror repository like: aws_account_id.dkr.ecr.region.amazonaws.com/docker/library/node You pull from ECR just like you would from Docker Hub: docker pull aws_account_id.dkr.ecr.region.amazonaws.com/docker/library/node:18 Example Use Case Final Thoughts Happy coding 👨🏻‍💻 💡 Enjoyed this?

JavaScript objects are at the heart of nearly every web application today, making it easy to organize and access data with simple key/value pairs. Yet there’s a detail many developers overlook: the ability to use spaces in those keys. Have you ever wondered if your object can have a key like "user name" instead of userName? It turns out you can—but it requires a bit of extra syntax. By wrapping keys in quotes and using bracket notation, you’ll gain the flexibility to match labels exactly as they appear in external data or UI designs. Understanding this trick helps you avoid unexpected bugs and keeps your code predictable. In JavaScript, object keys without spaces follow an identifier pattern: const person = { firstName: 'Alice', age: 30 }; Here firstName and age act like variable name…  ( 5 min )

Introduction Node.js runs on a single thread to execute JavaScript code but still handles thousands of concurrent I/O operations without blocking. How can a single-threaded runtime perform so much work at once? The secret is its event loop and asynchronous I/O model, powered by libuv and a small worker thread pool under the hood. Grasping this pattern helps you write non-blocking, high-throughput applications. At its core, Node.js uses a single thread to run your JavaScript, thanks to Google’s V8 engine. This thread processes your script, executes functions, and manages variables. It does not spawn a new thread for every client request. Instead, it relies on an event-driven architecture. Tip: Keep CPU-intensive work out of the main thread to avoid blocking the event loop. Key points: A s…  ( 5 min )

With 86.5 thousand stars on GitHub, FastAPI is among the most popular backend frameworks given its lightweight and modular design and ease of use. While Express.js uses the Node.js and JavaScript ecosystem and has access to its libraries and tools, it lacks the type safety of FastAPI and requires external tools such as TypeScript.…  ( 6 min )

JavaScript, being a single-threaded language, can only process one task at a time. This can result in long wait times for complex tasks, as the script will be blocked from executing any other tasks until it has been completed. To tackle this, JavaScript offers asynchronous programming, which allows the script to continue executing other tasks while it waits for an asynchronous task to complete. In this blog, we’ll explore the basics of asynchronous programming in JavaScript and how it can be achieved through the use of callback functions, promises, and async/await. A callback function is a function that is passed as an argument to another function and is executed after the main function has been completed. Callbacks are used in asynchronous programming to wait for a task to complete before…  ( 5 min )

As developers, we're constantly striving to build performant and efficient applications. One common challenge arises when dealing with events that fire rapidly, like input changes, scroll events, or window resize operations. These can lead to unnecessary re-renders, API calls, and a sluggish user experience. That's where debouncing comes in! ✅ What is Debouncing? Think of it like this: if you're typing into a search bar, you don't want an API call to happen after every single keystroke. Debouncing waits for a brief pause in your typing before making the call, drastically reducing the number of requests and improving responsiveness. ✅ Why is it Crucial for React Developers? Reduce API calls: Prevent excessive network requests for search suggestions, form validations, etc. Optimize re-renders: Minimize the number of times components re-render due to rapid state changes. Improve user experience: Provide a smoother, more responsive interface by avoiding UI jank. ✅ A Simple Example (Conceptual): // Without Debounce // Every keystroke triggers handleSearch // With Debounce // handleSearch only triggers after a pause in typing You can easily implement debouncing using a custom hook in React or a utility function in plain JavaScript. Libraries like Lodash also offer a robust _.debounce() function. ✅ Ready to Optimize Your React Apps? If you're building interactive web applications, mastering debouncing is a game-changer.

Understanding the super Keyword in Java When working with inheritance in Java, super keyword plays key role in accessing members (variables, methods, and constructors) of parent class. It helps avoid confusion when subclass and superclass share similar names for methods or variables. super in Java? In Java, super is reference variable used to refer to immediate parent class object. Whenever you create an instance of subclass, an instance of its superclass is also created, and super points to it. super in Java Java allows you to use the super keyword in three main ways: If subclass has a variable with the same name as the parent class, use super to refer to the parent’s variable. class Parent { int x = 10; } class Child extends Parent { int x = 20; void display() { System.out.println("Child x: " + x); System.out.println("Parent x: " + super.x); } } If method is overridden in the subclass, you can still access the parent class version using super. class Parent { void show() { System.out.println("This is Parent"); } } class Child extends Parent { void show() { System.out.println("This is Child"); super.show(); // Call parent method } } Use super() to call the constructor of the parent class. It must be the first statement in the child class constructor. class Parent { Parent() { System.out.println("Parent Constructor"); } } class Child extends Parent { Child() { super(); // Must be first System.out.println("Child Constructor"); } }  ( 3 min )

Factory Pattern belongs to the Creational family of design patterns. how objects are created, and how to make that process cleaner, scalable, and easier to manage. WHY would you use it? When you’re just starting out, things look innocent, if type == "Email" return new EmailSender() else if type == "SMS" return new SmsSender() And it works! Until, you need to support 8 more types, copy this block across 6 services, and one tiny change breaks 4 things at once. This is the tipping point where Factory Patterns saves the day.

Common Causes Mutating state directly instead of using {setState} or {useState} setter Using stale closures inside event handlers or effects Forgetting to add dependencies in {useEffect} Memoization (React.memo) preventing updates unintentionally Quick Solutions Never mutate state directly — always create new copies with spread operator or Object.assign. Check your hooks’ dependency arrays — make sure you include everything you use inside useEffect. Use functional updates if state depends on previous state: setCount(prev => prev + 1); Be careful with memoization — if a component uses React.memo, ensure its props actually change. Bonus Debug Tip Add console logs inside render or effects to track when your component updates.  ( 3 min )

As a Web Developer focused on backend systems, I’ve found that using Rust and Go together creates a powerful stack for building scalable services. Rust gives me low-level control, safe concurrency, and unmatched performance — perfect for async-heavy workloads like caching layers and job queues. Go keeps things fast and readable for services like HTTP APIs and CLI tooling. Its simplicity is perfect for REST endpoints and internal tooling. I recently shipped a system using both: Go-based API layer (stateless, lightweight) Rust-based async job handler (memory-safe, multithreaded) As a Web Developer, I’ve learned that picking the right language for the right piece of the system is what keeps things scalable and sane.

Forza Motorsport developer Turn 10 has reportedly shut down its Motorsport division and become a support studio for Playground Games’ Forza Horizon series after laying off over 70 employees. This change is part of a larger wave of Microsoft gaming shake-ups—The Initiative’s Perfect Dark was canceled, Rare’s Everwild got shelved, a ZeniMax Online MMORPG was scrapped and even a Romero Games FPS never saw the light of day—leaving Motorsport fans to wonder if the franchise will ever return.  ( 3 min )

European game publisher group Video Games Europe has fired back at the Stop Killing Games campaign just as it hit the signature bar for an EU Citizens’ Initiative. They say killing off online services is never a snap choice and needs to stay on the table when servers just aren’t commercially viable—plus, gamers already get a fair heads-up under consumer-protection laws. On top of that, VGE warns that forcing private-server solutions would rip away vital data-security and content-moderation safeguards, leaving rights holders on the hook. Since a ton of today’s titles are built as always-online experiences, they argue, banning service shutdowns outright would hamstring developers and jack up costs sky-high.  ( 3 min )

New data from Circana (via the Wall Street Journal) shows 18- to 24-year-olds in the US are slashing their weekly video game spending by nearly 25% year-over-year, compared with a more modest 13% drop in their overall retail outlay (Jan–Apr 2025). Other age groups are still spending more on games, just not quite as fast as before, highlighting how student loans, shaky job prospects and credit-card debt are pinching Gen Z wallets. Meanwhile, rising console and game prices aren’t helping: Xbox’s Series X/S line now starts at $600 and first-party titles are creeping up to $80 (Outer Worlds 2, anyone?), while Nintendo’s Switch 2 launch games clock in at $80 and $70. Younger gamers are feeling the squeeze harder than most.  ( 3 min )

David Dastmalchian—the underrated character actor you’ve probably spotted in everything from indie gems to buzzy horror flicks—has officially been tapped to play the big bad M. Bison in Legendary’s live-action Street Fighter movie. It’s the biggest single role of his nearly 20-year career (sorry, “The Life of Chuck” fans), and comes on the heels of his standout turn in the viral frightfest Late Night with the Devil. Reps for Legendary aren’t talking, but we’re guessing Dastmalchian’s signature mix of intensity and off-kilter charm will make the dictator of Shadaloo a villain to remember.  ( 3 min )

bbc.com TL;DR Francis Ford Coppola’s 1979 Vietnam-set epic Apocalypse Now was so chaotic it mirrored the madness of its setting: a year-long shoot instead of five months, budget blowouts, recast leads (Harvey Keitel out, Martin Sheen in), typhoons flattening sets, actors falling ill or partying hard, and an overweight Marlon Brando forcing a last-minute rewrite. Eleanor Coppola’s 80 hours of behind-the-scenes footage—now restored in 4K for the re-released Hearts of Darkness—reveals the crew battling hookworms, Biblical rains and “homesickness” rivaling that of actual soldiers. Documentarians Fax Bahr and George Hickenlooper pieced together this “Idiodyssey,” complete with audio tapes of a beleaguered Coppola wrestling with the film’s ending. Despite real-life drama—editors on the run with stolen reels, endless reshoots and Coppola’s personal financial ruin—the project survived, became a cinematic milestone, and remains “something nobody will ever be able to do again,” as Bahr puts it.  ( 3 min )

A common misconception is that only programmers can contribute to open source project. Being a programmer of course make it possible for you to make changes to the source code of the application, Firefox, VLC, Moodle, or mdbook. A few of the areas where one can help: QA - Quality Assurance. There is always a need to help checking the quality of these open source projects. Someone needs to act as the product manager trying to understand what the users would like to have and if that's something the product should actually do. Someone needs to provide customer support. Someone needs to write documentation. Maybe there is a need for creating "marketing material". That could be a nice web site for the project, a logo, nice images etc. There is also a need to help with fundraising. Many open source projects and many open source developers could do a lot more if they got some payment for their time. How do you contribute to open source?  ( 3 min )

🌍 What Is Ethereum? A Glimpse Into the World Computer Imagine a world computer that runs code exactly as programmed, without downtime, censorship, or third-party interference.

Introduction In 2025, WebAssembly (Wasm) has evolved from a niche browser-centric technology to a cornerstone of full-stack web development. Initially designed as a portable compilation target for running high-performance applications in browsers, Wasm now powers everything from client-side interactivity to serverless backends, edge computing, and even blockchain smart contracts. Its ability to execute code at near-native speed, combined with its language-agnostic design, has made it indispensable for developers building scalable, secure, and efficient applications. This article explores Wasm’s trajectory into mainstream full-stack development, its current use cases, and the tools shaping its ecosystem. 2015–2020: Browser-Centric Origins Wasm debuted as a Web Standard in 2015, enabl…  ( 5 min )

"The web is so complex now" "Ugh, I wish I didn't need all these different tools and build steps just to make a website" "But I don't want to give up all the convenience I'm used to" Sure, that's enough strawmen to pretend to justify this sillyness. Vue invented this phenomenal idea of a "Single file component". Where you break up your app into UI component chunks (separation of features), and within each component, there are 3 dedicated places for the 3 languages of the web. Each with their own focus (separation of concerns). Technically you can use Vue via a CDN and it works, but out of the box, they don't have a way to support these wonderful .vue files in the browser. So we need to pull in a library that can dynamically download .vue files on the fly, and also process them to regular J…  ( 6 min )

I remember the first time someone asked me to explain what "rendering" means in programming. I fumbled through a technical explanation about DOM trees and paint operations, and watched their eyes glaze over completely. That's when I realized I didn't really understand it myself - I just knew the buzzwords. After years of debugging sluggish animations and optimizing app performance, I've learned that rendering is actually a pretty straightforward concept once you strip away the jargon. Let me explain it the way I wish someone had explained it to me. At its core, rendering is just the process of turning your code into something visual on a screen. Think of it like a translator who takes your written instructions and turns them into pictures that users can actually see and interact with. When…  ( 6 min )

Hello everyone, I'm Frontend Xiaoga. Lately, I've noticed that AI has become quite unhelpful in my work. It often generates a lot of useless information or completely misunderstands what I mean. This happens because the problem isn't described clearly enough. It's like two strangers trying to communicate: if one speaks in riddles, the other will struggle to understand. However, we humans always hope the other person can read our minds, requiring minimal language for them to grasp our thoughts. That's why I created a prompt optimization tool. It can analyze our needs and tell us what information the AI requires to produce better results. More articles Let me give you an example. HolyShit!! It's only a slight improvement, but the optimizer provides an analysis of the problem. For instance, it tells us which variables are needed to generate a picture of a beautiful woman. We can then modify this structured prompt based on our preferences, like making her wear pink pants. LangChain try { const { modelName = "gemini", prompt = defaultPrompt } = options; const promptTemplate = ChatPromptTemplate.fromTemplate(prompt); const model = modelName === "cloudflare" ? this.cloudflareModel : this.googleModel; console.log("Creating RunnableSequence chain"); const chain = RunnableSequence.from([ { query: new RunnablePassthrough(), }, promptTemplate, model, new StringOutputParser(), ]); const result = await chain.invote(query); return result; } catch (error) {}  ( 3 min )

Overview How difficult is it to achieve Unreal Engine-style procedural context debugging? Turns out, it might be easier than expected. In this dev log, we won't implement all the fancy animations or full-featured GUI yet, but we will derive a practical, functional debugger GUI. This interface allows users to step through a procedural program and observe its execution flow in real time. Procedural contexts are hard - not necessarily to implement (they're actually simpler than dataflow contexts in interpretative runtimes, where you just step over nodes), but hard for users. The main issue is statefulness: once there's state, there's the potential for mistakes, side effects, and confusion. From an implementation standpoint, the hard part is debugging. Without visibility into execution, it…  ( 5 min )

Over the years, I’ve met countless individuals eager to transition into tech. They’re motivated, they’re taking courses, and they’re networking. But there’s often one key piece missing: they don’t know what niche in tech they want to go into. Recently, I participated in a webinar as a guest speaker, and this topic arose again. A recurring pattern emerged. People are diving into tech without a clear understanding of the diverse opportunities available or what roles suit them. And without that direction, it’s easy to feel overwhelmed, lost, or like an impostor. If that sounds like you, I want you to know you’re not alone, and it’s okay not to have it all figured out right away.

why not bring that experience to the web? That’s how my personal site turned into a retro-style operating system UI — complete with pixel-art icons, draggable windows, fake file explorers, and nostalgic system sounds. The whole interface is built to feel like you're using a hybrid of Windows 98, early XP, and a bit of DOS for flavor. I designed (or curated) a custom sprite sheet of 24 pixel icons — from the classic My Computer to Minesweeper and floppy disks — all rendered in a consistent 16-bit pixel style with transparent backgrounds for web or game use.

If I had a dollar for every time someone has asked me, "I am not a natural-born writer, how can I get better at technical writing?", I'd probably own a private jet. My answer is to follow a technical writing process.

Even 'natural born' writers will struggle without a writing process.

Em desenvolvimento de software, os Padrões de Projeto surgem exatamente para oferecer soluções elegantes a problemas comuns. Um desses padrões essenciais é o padrão Factory, parte dos chamados padrões criacionais. Em essência, o padrão Factory permite criar objetos sem expor ao código cliente a lógica de criação desses objetos. Em outras palavras, seu principal objetivo é instanciar classes concretas sem que o cliente precise saber exatamente qual classe está sendo usada, delegando essa decisão para um componente central ou subclasses especializadas. Isso traz mais flexibilidade e mantém nosso código limpo e extensível. Para ilustr…  ( 10 min )

"A walkthrough of designing an AI agent that rewrites its own strategies using recursive optimization, inspired by meta-learning and AGI research." What if an AI could improve itself without external supervision? That question became the seed for this project. Build a recursive self-improving agent — a system that: Writes its own prompts Evaluates and critiques its past runs Updates internal strategies autonomously Learns over time via feedback loops Inspired by meta-learning, recursive self-reflection, and AGI architecture principles. Component Tools/Approach LLM Engine Ollama (local inference) Evaluation Logic Chain-of-Thought + Self-Critique Memory JSON logs + vector database Planning Dynamic Prompt Rewriter Tuning Self-generated hyperparameter sweep The core of the agent is a recursive reasoning loop: Draft an initial plan (prompt) Execute it using the local LLM Evaluate outcome quality Rewrite plan if performance is subpar Retry and compare outcomes This loop continues until a threshold of self-satisfaction is reached. [Plan] → [Run] → [Critique] → [Update Plan] → [Repeat] 🧪 Key Capabilities 🌱 Why This Matters 📚 What's Next 📂 Open Source Thanks for reading — and if you're building something similar, I’d love to connect 🚀  ( 4 min )

Ever spent hours building a feature only to realize you’ve coded yourself into a corner? Or duplicated the same logic across files thinking, “There has to be a better way”? That better way often has a name — and it’s probably a design pattern. Welcome to a world where your codebase becomes cleaner, smarter, and more scalable — not with magic, but with well-established architectural wisdom. In this series, we’ll explore the powerful design blueprints every serious developer should have in their toolkit. Design patterns are proven, reusable solutions to common problems that occur in software design. They represent best practices refined through years of experience by object-oriented software developers. Rather than providing code that can be copied and pasted, design patterns are conceptual …  ( 4 min )

The Problem Many patients who require specialty medications often struggle to find and complete the necessary enrollment forms. These forms are typically hosted on pharmaceutical websites, hidden within multiple tabs, or presented as complex PDFs with little guidance. This problem is particularly common for patients who are not tech-savvy or who are under financial stress. Even finding something as basic as the enrollment form for a drug like Olumiant can be a challenge. To solve this, I created StartForms.org, a simple static website that organizes and links directly to official enrollment forms for over 40 medications. The project uses a minimal tech stack, focusing on clarity and speed: Clean, mobile-friendly HTML and CSS Static pages hosted for fast loading Descriptive URLs and on-page SEO No login, no ads, no distractions Each form page includes a short description, eligibility notes, and an option to either fill the form online or download the PDF. If a patient needs the Olumiant Enrollment Form, they can access it directly here: Download the Olumiant Enrollment Form This page includes a preview, instructions for completion, and a link to print or save the official form. Creating a resource like this reaffirmed that: Simple, purpose-driven web pages still solve real problems Clear information architecture improves accessibility Patients benefit when we remove unnecessary complexity The plan is to continue expanding the number of supported medications and improve accessibility through: Multi-language support (starting with Spanish and Urdu) Categorization by condition or drug type Adding a lightweight JSON API for developers building similar tools Projects like this don’t require a full-stack framework or a large budget. A focused idea and clear execution are often enough. If you're working on projects that improve access to healthcare through technology, I’d love to connect and share insights. You can explore more forms and patient tools at StartForms.org.  ( 3 min )

What annotations are What beans are What the Spring container is What dependency injection is Why, when, how to use all of them Understanding Annotations, Beans, Spring Container & Dependency Injection in Spring Boot If you're learning Spring or Spring Boot, you’ll constantly hear terms like: @Component, @Autowired, @bean Spring container Dependency Injection (DI) Beans And how do they help make your application clean, modular, and powerful? ** What are Annotations in Spring?** In Spring, annotations are special markers (starting with @) that tell the Spring framework to do certain things automatically. In Spring, a Bean is just a Java object managed by the Spring container. For example: This MyService class becomes a Spring Bean because it’s annotated with @Component. The Spring container is the core of the Spring Framework. ** It is responsible for:** Creating objects (beans) Managing their lifecycle Injecting dependencies into them Configuring them based on annotations or XML Think of the container as the brain that runs your Spring app. How does it work? When your app starts: Spring scans your classes (like @Component, @Service) Creates and stores them in memory Connects everything together automatically What is Dependency Injection (DI)? Dependency Injection means that an object’s dependencies are provided (injected) from the outside, instead of the object creating them itself. Spring takes care of creating the object and injecting it where needed. Why Use Dependency Injection? Loose coupling – makes code easier to test and maintain Better modularity Cleaner code with fewer new keywords How Spring Does Dependency Injection Spring supports 3 types of DI: Spring will automatically create the Engine bean and inject it into Car.  ( 3 min )

Author: Tobie Morgan Hitchcock We're at an incredible inflection point in AI. For the past few years, generative AI has rightly commanded the spotlight, with its ability to create, design, and synthesise information. We are now at the point of another paradigm shift with Agentic AI. This isn't just about faster information processing. It’s about enabling systems to act with more independence, context, and coordination. Generative AI introduced models that can learn and create based on prompts. Agentic AI builds on top of that and adds the critical capabilities of acting on its own and collaborating with both humans and other agents. It picks up precisely where generative AI leaves off, taking extracted and summarised information and transforming it into autonomous action, with limited or n…  ( 6 min )

Introduction In the previous article How to Build a ReAct AI Agent for Cybersecurity Scanning with Python and LangGraph I explained how to build a simple ReAct Agent to scan a web target for vulnerabilities. But the scope of work for cyber security audits is bigger than just scanning. It includes: Scanning Stage - get information about possible vulnerabilities in the target. Attacking Stage - try to exploit vulnerabilities and prove our hypothesis from the scanning stage. Reporting Stage - create comprehensive report for company which requested audit to apply fixes. And to build this I tried to go with simple graph first but then realized that this approach is not flexible and violates "Single Responsibility" from SOLID. That's why I have built the pipeline of agents where each agent is…  ( 8 min )

Written By CortexFlow A few years ago, searching for something online essentially meant typing a few keywords and hoping the algorithm guessed what you meant. The results weren’t always wrong (they were actually pretty decent) but they were rarely right in the way you wanted. They didn’t understand context, or intent, or the quiet nuance behind a question. You basically searched for a book and just got a long list of titles. You asked a question and got a dump of related documents. Today, that’s changing very fast. Thanks to generative AI and powerful language models, our systems are becoming more than reactive engines. They’re starting to develop some forms of understanding. They can summarize, answer, reason, and even “remember”. But beneath this newfound intelligence lies a silent arch…  ( 6 min )

Have you ever needed to count elements or sum variables across elements and then use the result as a CSS variable? No JavaScript involved. I'll show you how it can be done. The solution is kind of insane, but beautiful. It took tens of hours of thinking, trying, and failing—again and again—until it was finally accomplished. Why would one even bother? It opens up fascinating possibilities: Changing layout based on content without needing media or container queries Dynamically adjusting cells in grid/flex based on their position in the container Determining whether a grid cell is in the first row or not From the beginning, it was clear that a full-featured solution must be implemented using CSS counter(). You can count elements with the :nth-child selector or with the brand new sibling-index…  ( 6 min )

If you're building a chatbot, search engine, or any AI application that needs to "know stuff," you've probably bumped into a hard truth: Large Language Models (LLMs) can't access your private or domain-specific data unless you feed it to them. Whether it’s product documentation, internal policies, or real-time records, large language models can’t access external knowledge unless you explicitly feed it to them. Enter RAG (Retrieval-Augmented Generation). RAG combines the creative power of an LLM with the factual accuracy of your own data. At its core, it relies on semantic search finding the most relevant pieces of text based on meaning, not just keywords. Instead of asking an LLM to hallucinate answers, RAG pipelines first retrieve relevant content from your data sources, then pass it into…  ( 5 min )

Still no live demo yet… but hit a major milestone today: DevConnect can now fetch GitHub repos and support image/video uploads—despite a hell of a learning curve! 🧑‍💻 What’s Working (So Far): ✅ GitHub Integration: DevConnect now fetches public repos from GitHub—it feels amazing to see real code showing up in the profile! ✅ Media Uploads: Image and video uploads work (thanks, Cloudinary), even though I accidentally uploaded test videos 30 times before fixing my file-path logic. ⚠️ Challenges Along the Way: 🐞 That ONE async bug: a missing await caused duplicate uploads—my Cloudinary account saw a surge in nonsense. Debugging that definitely earned me ☕. 🧩 State management chaos: toggling between Context & Redux Toolkit had me rethinking my approach—but it's in a solid place now. 🧭 UI polish: making responsive post cards look nice on mobile took way more effort than I expected. 🎯 Why Keep Building Blend social + code sharing—so devs don’t have to juggle GitHub and Twitter separately. Create an early beta community, whose feedback will help shape features like comments on repos and like buttons. Note: While there’s no live button yet, every bug fix and user test brings it closer. I’m also researching how to tease development publicly—informed by advice to build excitement early on 🧠. What feature matters most to you? Issues tracker? Project boards? Commenting on repos? Want to swing by the early demo? DM me—I’d appreciate any feedback. *DevConnect is still in progress: no live demo yet. *But it's already pulling real GitHub repos + uploading media. *Lots of cleanup & polish still ahead—just sharing wins and lessons early 👊.

Recently, a client came to us with an unusual issue during their TFT LCD prototyping phase. Everything powered on correctly, the screen was displaying content — but the colors were completely off: washed-out contrast, heavy blue tint, and strange gradients. Their setup used an 18-bit RGB TFT display (6 bits per color: R[5:0], G[5:0], B[5:0]), but they were connecting it to a 24-bit RGB output (8 bits per color). They assumed the signals would “just work.” 🔍 Root Cause: This caused the GPU or controller to interpret the floating inputs as random values or logic highs, leading to abnormal gamma behavior and color distortion. ✅ Quick Fix: Mapping the higher 6 bits (R5–R0) of the 18-bit display to the upper 6 bits of each 8-bit color line (R7–R2, G7–G2, B7–B2) Tying the lower unused bits to ground The display instantly rendered clean, accurate color. 🧠 Takeaway: I'm part of a team that focuses on small-to-medium TFT LCD modules and system integration (touch + PCB). I'll be sharing practical tips like this from real projects — hope it helps someone in their next hardware build!  ( 3 min )

In 2021, I was deep in Salesforce development, reviewing pull requests, fixing edge cases, and trying to ship clean code. AI code reviews weren’t a thing back then.

What Is JSON? JSON (JavaScript Object Notation) is a lightweight format for storing and exchanging data. It looks like structured text using key-value pairs, and it's easy for both humans and machines to read. Example: { "name": "Paris", "population": 2148000, "area": 105.4 } PostgreSQL supports two ways to store structured data in a column: JSON and JSONB. JSON stores the data as plain text. It’s readable but slower for queries. JSONB stores the same data in binary format. It’s faster, allows indexing, and supports advanced filtering. The main advantage of using JSONB is that you can query individual fields inside the JSON structure using SQL. You can also sort, filter, and index values without splitting your data into multiple tables. For example, instead of creating a separate…  ( 6 min )

As AI is growing, traditional AI, multimodal AI, and edge AI represent distinct approaches with unique strengths. Here's a comparison to help developers understand their differences. What is Traditional AI? Task-specific: Built for narrow functions like classification or prediction. Centralised: Runs on cloud or server-based systems. Single-modality: Processes one data type (e.g., text or numbers). Reactive: Relies on pre-trained models or rules. What is Multimodal AI? Cross-modal: Handles text, images, audio, or video. Creative: Generates novel content like artwork or stories. Flexible: Adapts to diverse tasks with contextual understanding. Cloud-heavy: Often requires significant computational resources. What is Edge AI? Localised: Runs on edge devices for low-latency performance. Resource-efficient: Optimised for limited computing and power. Privacy-focused: Processes data locally, reducing cloud data transfers. Task-specific: Often tailored for real-time applications. Why It Matters Traditional AI excels in structured, repetitive tasks but lacks flexibility. Multimodal AI drives innovation in creative and cross-domain applications, ideal for developers building next-gen tools. Edge AI enables fast, private, and efficient solutions for IoT and mobile apps. Understanding these differences helps developers choose the right AI approach for their projects, whether it's automating workflows, creating multimedia content, or powering smart devices.  ( 3 min )

Unlike fixed resistors (stiff as old fence posts), it bends with the current, like a willow in a storm. Potentiometer (Pot): Three terminals, like three friends. It splits voltage—think of it as a volume knob for electrons, turning a roar into a whisper (or a whisper into a song). Core Superpower: Resistance ranges from 0Ω to 10 million ohms. No soldering, no spells—just twist, and the circuit bends to your will. Symbols & Secrets: The Language of Knobs Variable resistors speak in symbols—simple, but full of stories.

Artificial Intelligence (or Large Language Models, if we're being specific) are all the rage these days. What started as a novelty—AI generating poems, jokes, or essays—has rapidly evolved into a transformative force in software development. Not only can AI write fluent, coherent English, it can now write code at a blistering pace. Gone are the days of scouring Stack Overflow for the right snippet. Today, developers are pairing up with machines that understand natural language, anticipate intent, and fill in the blanks—literally—as they type. Editors like Cursor, Windsurf, and Claude are leading the charge, offering autocomplete on steroids. They predict what you’ll write next—sometimes before you’ve even thought of it. Traditional autocomplete tools simply finished off function names or s…  ( 4 min )

Cross-Site Scripting (XSS) is one of the most common — and dangerous — web application vulnerabilities. It allows attackers to inject malicious scripts into web pages viewed by other users, potentially leading to data theft, session hijacking, or unauthorized actions on behalf of users. In this post, we’ll look at the three major types of XSS attacks with real-world examples, and how the open-source SafeLine WAF helps block them effectively. XSS (Cross-Site Scripting) attacks exploit websites that don’t properly sanitize user input. By injecting malicious scripts into otherwise trusted pages, attackers can: Steal cookies or session tokens Redirect users to phishing pages Alter site content or behavior Stored XSS happens when malicious scripts are permanently stored on the target server — …  ( 5 min )

Good day, #DEVCommunity! It's mid-2025, and AI isn't just in our tools anymore; it's deeply embedded in the services we build, the decisions our applications make, and increasingly, the fabric of society. Living here in Victorias City, Philippines, even far from Silicon Valley, we're seeing the local impacts—from AI-driven customer service to automated agricultural tech. This ubiquity brings us to a critical, often uncomfortable, question: As developers, how much responsibility do we truly bear for the ethical implications of the AI systems we create? We're beyond the "AI will solve everything" phase. We're now confronting the real-world consequences of: Algorithmic Bias: Models trained on skewed data leading to unfair outcomes in lending, hiring, or even justice systems.

Power Pages uses the Bootstrap DateTimePicker library to render date and time fields on forms. This library offers a wide range of methods to customize and control the behavior of the date picker widget. To programmatically interact with the date picker, you can use jQuery to retrieve the DateTimePicker object associated with a specific field. Use the following code to get the instance of the date picker object. $("#field_id").next().data("DateTimePicker") Here, field_id is the schema name of the field. Once you have the DateTimePicker object, you can easily apply various configurations. For example, to disable future dates from the date picker widget use the following code – $("#field_id").next().data("DateTimePicker").maxDate(moment()) You can also set specific date ranges to select. For example, to limit the date picker to only allow selecting dates within 7 days before and after today, creating a 14-day selectable range. var datePicker = $("#field_id").next().data("DateTimePicker") datePicker.minDate(moment().subtract(7, 'days')) datePicker.maxDate(moment().add(7, 'days')) As you can see in the image below, only dates within 7 days before and after 16th May are selectable. You can refer to the official Bootstrap DateTimePicker documentation for a complete list of methods and customization options.  ( 3 min )

A debugging story about array parameters, pagination, and why choosing the right parsing function matters. One day, Marci, an intrepid Elixir developer, was building an admin panel for a Monster Bestiary. Everything was working smoothly until adventurers started reporting a bizarre bug: when they filtered by multiple monster types and tried to paginate through results, some of their selected filters mysteriously vanished. Adventurers would select both "Dragons" and "Goblins", set their page size to 15, and when they clicked "Next Page" - poof! - suddenly only "Goblins" remained in their filters. The Dragons had vanished without a trace.

It’s estimated that 80–90% of the world’s data is unstructured, with text files and documents making up a big chunk of it. Invoices are a perfect example of this chaos. Each vendor uses a different layout, with formats and terminology that vary wildly across industries. Totals might appear in headers, footers, or hidden deep in tables. Then there are smudged scans, odd fonts, and delivery charges mixed with line items. It didn’t take long for us to see why traditional systems built on regexes and static templates struggled to keep up. About a year ago, we hit a wall with invoice processing. The automation pipelines we had built for FMCG, healthcare, and logistics worked beautifully, but invoices were a whole different beast.

Member-only story -- Share Intro: New users being added to a server may seem harmless — especially if you’re managing it solo. But on a shared or internet-facing server, this can be the first sign of a breach. I learned this the hard way after noticing strange sudo activity from a user I never created. Here’s how I now monitor all user creations and how you can set up real-time email alerts on both Ubuntu and Red Hat. Why You Should Care About New Users A newly created user with sudo access can: Install malware Pivot into lateral movement Hide activity using rootkits Even without sudo, attackers use fake users for persistence — so catching it early is key. Monitor /etc/passwd in Real Time Using auditd Install auditd: # Ubuntusudo apt install auditd -y # Red Hatsudo yum install audit -y Create an audit rule: sudo auditctl -w /etc/passwd -p wa -k useradd-watch This tells the system to watch for writes/appends to /etc/passwd.

Member-only story -- Share Intro: You’ve isolated the server. You’ve grabbed the logs. You’re scanning for malware. But if you skip checking the sudoers.d directory, you might miss the real backdoor. In this post, I’ll explain why attackers love /etc/sudoers.d, how they use it to persist silently, and what I do to catch and clean it up. Unlike the main /etc/sudoers file, which is usually locked down and audited, the sudoers.d directory is often overlooked. Any file placed there with relaxed rules can silently grant root privileges — without changing the main sudo configuration. ✅ What attackers do: They drop a file like /etc/sudoers.d/xyz with a line like: hackeruser ALL=(ALL) NOPASSWD:ALL This gives their user full sudo access without a password — even after reboots. Run: sudo ls -l /etc/sudoers.d/ Then inspect each file’s content: sudo cat /etc/sudoers.d/ Look for: Unknown usernames Read Full Blog on Medium Here  ( 3 min )

When designing APIs and data models, I prefer simplicity and avoid ambiguity. For date and time, programmers like using epoch time. This is the number of seconds or milliseconds since January 1, 1970. It requires just one integer field, making it easy to compare and manipulate. My favourite geek joke is that the world should switch from measuring time in hours and months to using megaseconds and gigaseconds. APIs are often crafted by backend developers who aim for simplicity. Sending epoch times as integers might be harsh. However, even if using the more human-readable ISO string format (YYYY-MM-DDTHH....), requiring all time fields to be in UTC is just shifting responsibility onto others. Relying on the client to handle time zone conversion can lead to issues, especially if the time is en…  ( 4 min )

I Built a YouTube Livestream Bot Used by Big Creators – Now I Need Help Keeping It Alive Hi Devs 👋 I wanted to share a little open source project I've been working on: it's called Tsnip, and it's already being used by some big YouTube streamers — like @RakaZoneGaming (506K subs), @Exion (94K), and @BloodLineYT (63K). Tsnip is a YouTube livestream bot that lets viewers save epic moments in real-time by typing !ts in chat. Behind the scenes, Tsnip receives requests via Nightbot, and after the stream ends, it automatically comments all saved moments back onto the YouTube video — so creators (and their communities) can revisit the highlights without having to rewatch the whole thing. No editing. No scrubbing through 3-hour VODs. Just raw moments, saved collaboratively by the chat. This started as a small personal tool, but after sharing it with a few creators, it spread fast. Now, streamers are using it to let their viewers "co-create" content highlights — and it's improving community interaction too. Used by: @RakaZoneGaming (506K subs) @Exion (94K subs) @BloodLineYT (63K subs) ...and many more Mentioned in README.md GitHub: https://github.com/jaypatel208/tsnip.git 💸 Why I Need Support As usage grows, so do the costs — YouTube API quota upgrades, Vercel usage, etc. I want to keep Tsnip free and open-source for the community, but I’ll need help sustaining the infrastructure long-term. If you like what I’m doing and want to support it, consider becoming an early sponsor via GitHub Sponsors. Every bit helps! ⭐ Star the repo: https://github.com/jaypatel208/tsnip.git 🧪 Try the bot if you're a creator 🤝 Sponsor if you believe in open tooling for creators 📣 Share it with someone who streams! 📖 Read the full story on Medium - Learn about the journey behind Tsnip Thanks for reading.

Ah. I faced a problem in my 25. I often watch YouTube via my PC, but unfortunately I need to eat sometimes in my kitchen. This is not a reason to turn the video off - it's rather the opposite.

It was around 11:47 PM on a random Tuesday night when I stared at the same LeetCode problem for the third hour in a row. “Hard” problems had started feeling less like a challenge and more like mental torture. I was tired. Not just physically, but deeply and spiritually tired of chasing a number on a profile. That night, I closed the LeetCode tab, stepped away from the screen, and told myself: “I quit LeetCode.” But the story doesn’t end there. Strangely, it was the moment I quit LeetCode that I actually started getting better at real coding. Let me take you through that journey. When I started LeetCode, it felt like a rite of passage.

Hello Fellow, welcome to this, My Archive initiative, Well, I could say a lot here, but I’ll simply say: I enjoy what I do and the world around us, but sometimes I can feel overwhelmed by the amount of information available and the non-stop pace of this crazy world… there is too much to know, too little time, and an entire life to live outside the screen. Exercise regularly. Eat well. Seriously. This blog is a way for me to cope, relax, and document things… My idea for this blog is to record my different attempts and approaches to technologies and tools that might be new to me, documenting my journey through them and storing and hopefully sharing the knowledge and resources I've gathered along the way. Just another engineer, trying to improve, share, and learn. And yes, English is not my first language… in case you read some weird English, it’s not intentional… probably… In any case, feedback is more than welcome.

This benchmark explores how well AI models handle the processing of complex tables from construction drawings. Read on to learn: Which AI model reached 100% accuracy on simple architectural schedules — and outperformed competitors by 20–60% in overall table extraction, Why Google’s layout parser failed to detect door and window schedules entirely — and which tools proved reliable in real-world conditions, How well modern AI services handle complex layouts, multi-line cells, and measurement data — and which ones hallucinate or fabricate table content. In architectural and construction documentation, schedules refer to organized sets of supplementary data, usually displayed in table format. These tables contain detailed information that would otherwise overwhelm and clutter the main drawings…  ( 7 min )

Building Intelligent Conversations with Google Cloud Dialogflow API Imagine a global logistics company struggling with a high volume of customer inquiries about shipment tracking. Each call to their support center requires a human agent, leading to long wait times and increased operational costs.

Teamwork in Motion – CSS Art Tribute to Office Culture This is a submission for Frontend Challenge: Office Edition sponsored by Axero, CSS Art: Office Culture. I wanted to capture the essence of everyday office life — the little things that make a workplace feel human: hallway chats, shared mugs, sticky notes, plants, and that classic water cooler. This piece, titled "Teamwork in Motion," is a lighthearted tribute to those simple yet meaningful moments. I was especially inspired by both real offices and the fictional ones that stick in our minds, like Dunder Mifflin. You can find the code and project files inside the repository: GitHub Repository: https://github.com/Discovered12345/CSS-Office-Art If you'd like to host or embed it, feel free to use CodePen or GitHub Pages. The entire scene is created using only HTML and CSS — no JavaScript or external libraries involved. This project was built entirely with semantic HTML and CSS, using only 358 lines of code to create a complete office scene. Every element — from the 18px-wide coffee mug handle to the 45px-tall characters — was crafted with box-model fundamentals: /* Example of CSS craftsmanship */ .head { width: 45px; height: 45px; background: linear-gradient(to bottom, #ffccbc, #d7ccc8); border-radius: 50%; /* Created facial features with ::before/::after */ } I grant Axero a worldwide, royalty-free license to display this project for promotional or marketing purposes, with credit.

You're given a list of events, each defined by a start day, end day, and value. You can attend at most k events, and events cannot overlap (inclusive on end day). Your goal is to choose a combination of events to maximize the total value. This is a dynamic programming problem with sorting and binary search. The strategy involves: Sorting the events by start day. Using memoization to track the best value at each step. For each event, choose to either: Skip it. Attend it and move to the next non-overlapping event. The trick is efficiently finding the next non-overlapping event using binary search. class Solution { public: static uint32_t maxValue(const std::span> in_events, const uint32_t k) { const uint32_t num_events = in_eve…  ( 5 min )

TL;DR: Free tool to split images into grids. No uploads, no signup, runs entirely in your browser. Last year, I was helping my girlfriend create one of those cool Instagram grid posts where a single image spans across 9 tiles. We tried several online tools, but they all had issues: Most required uploading photos to random servers (privacy nightmare) Others had terrible UI or added watermarks Some only worked for specific grid sizes The "free" ones weren't actually free After spending 2 hours fighting with these tools, I thought: "This should be simple. Why isn't there a decent solution?"

Hey #DEVCommunity! It's a beautiful Tuesday here in Victorias City, Negros Occidental, and as I look out at the sugarcane fields, it gets me thinking about how our local context here in the Philippines connects to the global tech landscape. Specifically, I've been reflecting a lot on sustainable tech and how it's not just a Silicon Valley concept, but something incredibly relevant, even here in our province. For a long time, the focus in our local tech scene has rightly been on building skills, securing remote work, and contributing to the digital economy. But as more of us, myself included, delve deeper into cloud computing, data science, and even local initiatives, the environmental footprint of our digital lives becomes more apparent. Why sustainable tech matters to me, right here in Ne…  ( 4 min )

Hello, I’m Simon, the developer behind Cabin Crew Life Simulator. The last time I wrote a devlog was when our game had just launched and unexpectedly received such a warm welcome from the community. It’s only now, nearly a month since my mother passed away, that I’ve found the strength to return to work and write to you again. But this won’t be a typical devlog. This one is special. I want to share a more personal story with you, what happened behind the scenes, beyond the glow of the screen and the early success of a game built by just two people. It’s about the gaps between updates, and about a mother who supported us wholeheartedly, right up until her final moments. Cabin Crew Life Simulator is an indie simulation game about the life of airline crew members, developed entirely by just t…  ( 9 min )

Hey devs! 👋 A solid project structure saves time, avoids bugs, and makes scaling easier. Whether you're solo or on a team, here's how to keep your codebase clean and scalable! 🚀 🧱 1. Use a Modular Folder Structure Split your project into feature-based or domain-based modules. Example: /src /auth /dashboard /shared /utils ✅ Easier to scale and navigate 📦 2. Group by Feature, Not by Type Instead of grouping files by type (components, services, etc.), group them by feature. Before: /components /services /pages After (Better): /profile ProfilePage.tsx profileService.ts profileSlice.ts ✅ Everything related stays together 🧩 3. Isolate Shared & Common Code Create dedicated folders like /shared, /common, or /lib for reusable logic, components, and helpers. ✅ Keeps DRY (Don't Repeat Yourself) 🛠️ 4. Standardize Naming Conventions Stick to consistent naming for files, components, and folders. Examples: camelCase for variables/functions PascalCase for components kebab-case for file names (optional but consistent) ✅ Makes collaboration smoother 🧪 5. Co-locate Tests with Code Place test files next to the code they test. Example: /auth login.ts login.test.ts ✅ Easier to find and maintain 🚦 6. Use Index Files for Cleaner Imports Use index.ts files in folders to simplify imports: Instead of: import { LoginForm } from '../../auth/components/LoginForm'; Use: import { LoginForm } from '@/auth'; ✅ Cleaner imports 📐 7. Separate Config and Environment Files Keep config, environment, and constants in their own folders. /config /env /constants ✅ Keeps app logic clean 📈 Bonus: Keep It Evolving Your structure doesn’t have to be perfect from day one. It should grow and adapt with the project. ✅ Start simple 💬 What’s your favorite project structure tip? Share it below! 👇  ( 4 min )

For farmers, gardeners, and ranchers, protecting crops and livestock from pests is a daily challenge. Pesticides are often a key tool in achieving this, but they also frequently face public scrutiny and a lot of misinformation. It's important to understand the science behind pesticide use, separate fact from myth, and be aware of current regulations. This article aims to provide a clear, balanced look at pesticides, helping you make informed decisions for your operation. Public perception of pesticides is often colored by fear and sensationalized media reports. Many concerns are based on misconceptions rather than solid scientific evidence. While it's true that some pesticides can pose risks if misused, modern pesticide development and regulation have significantly reduced those risks com…  ( 4 min )

Today's Focus: Performance Improvements Based on Lighthouse Audit Following feedback from Lighthouse, I tackled several areas to improve performance, accessibility, and overall user experience. Button Component Unification To reduce redundancy and ensure consistent behavior and styling, I consolidated button components into a single shared version. This simplifies the codebase and helps enforce a consistent UI across the app. Replacing Hero Video with Preloaded Image The hero section previously used a video background, which delayed the First Contentful Paint (FCP). To improve load times, I replaced the video with a preloaded static image as a placeholder. This allows users to see something immediately while heavier content loads in the background. JS-to-CSS Gallery Refactor I replaced the JavaScript-based gallery implementation with a pure CSS version. This not only reduces bundle size but also improves performance and maintainability. Tomorrow’s Plan: Continue Optimization I’ll continue addressing Lighthouse’s suggestions and explore additional enhancements to reduce layout shifts, improve asset delivery, and optimize image handling. Performance tuning is an ongoing process — every millisecond counts when it comes to user experience. tags: nextjs, performance, lighthouse, frontend, css  ( 3 min )

This is a submission for the World's Largest Hackathon Writing Challenge: Building with Bolt. Just finished the World's Largest Hackathon with Bolt! With zero frontend experience and just before starting a new job, I went all-in: 100+ hours of YouTube tutorials, learning the SOTA in vibe coding, agentic frameworks, and how teenagers are cranking out text-to-25k MRR apps during their lunch breaks 🫠 Key learnings? Generic building = generic sites. Use components from 21st.dev, shadcn, react-bits, anime.js, tweakcn to really stand out Your final product won't match your vision—embrace it! AI agents LOVE overwriting your work. Save often, discuss changes first, don't be afraid to modify the code directly It costs more to use a cheaper model. Upgrading to Claude sonnet 4, saved me 10x the iterations. Game changer. BUILD ONE FEATURE AT A TIME. Building too much create AI confusion. Make a plan, and tackle each step one by one (consider using context engineering and PRPs) Go with the FLOW. I ended up pivoting mid way because my previous idea was scooped by Freysa.ai's Enchanted Product 😣 That's ok, the integration with Reddit came in handy!! (You can see where the pivot happened here) I realized the hardest problem was to find an idea...and may be that's where the opportunity is. If tech barrier is lower, then quality of idea and identifying target markets become more important. What did I actually build!? If you're curious about my project, head to https://stribe.me and ask it about your next big idea. It's free to try. Your customers could be waiting for you.

From Forgotten USB Drives to Cloud Revolution: How Drew Houston's Bus Ride Changed Computing Forever It's 2007, and Drew Houston is on a bus from Boston to New York. He opens his laptop, ready to work during the long ride, only to realize his USB drive—containing all his work—is sitting at home. This wasn't the first time Houston had forgotten his files, and his frustration reached a boiling point. "I was so frustrated – really with myself – because this kept happening. I never wanted to have the problem again," Houston later recalled. On that very bus ride, he started writing the code for what would become Dropbox.

Introduction Built an AI Agent using Strands Agents SDK from Amazon Web Services (AWS) which calls my Kubernetes MCP server. Read more to find out… AI Agents and Model Context Protocol are the most popular concepts in Gen AI now. Now I have created an AI Agent which calls MCP server to debug issues in my K8s cluster. Recently I created a Model Context Protocol (MCP) server for Kubernetes read-only operations. AWS has created an SDK for building AI Agents called Strands Agents SDK. Now it added support for MCP as well. I used Strands Agents SDK and built an AI Agent which calls my K8s MCP server and debugs issues in my running K8s cluster. This demonstrates the AI Agents ability to achieve goals by perceiving the environment, reasoning and acting upon it using available tools like MCP servers. I have built agents using Langchain/Langgraph before. Compared to that creating agents using Strands Agents is simple and straight-forward. Add to that you can now call MCP servers also. Icing on the cake is that Strands Agents supports any LLM and not only restricted to Amazon Bedrock. Thanks to LiteLLM you can call most of the LLMs using this library. Strands also supports Ollama for calling LLMs running locally. Really impressed with it. Below is my detailed demo of my AI Agent: What are you building with Strands Agents SDK? If you are new to my posts, I regularly post about GenAI, AI Agents, MCP, AWS, EKS, Kubernetes and Cloud computing related topics. Do follow me on LinkedIn and visit my website (https://vijay.eu/posts) where I have all my previous posts at one place.  ( 4 min )

Day Two: The Sleep Tracker Tab Is Live and Functional 😴✅ Today I took my first real step into connecting code with real-life usefulness. The Sleep Tracker section of my habit tracker app is now fully functional. It lets you: Slide to set when you fell asleep and when you woke up Automatically calculate your total hours slept Handle overnight sleep (e.g. 23:30 → 06:30 works!) Save the result to an SQLite database, locally on your machine This marks a big shift: from just seeing screens… to making them do something. I’m building this app not just to learn Python and mobile app dev — but to rebuild structure in my own life. Tracking sleep helps me stay mindful of energy, focus, and mental health. The goal is consistency, not perfection. Each section of this app — sleep, calories, workouts, running — is a tool for self-maintenance, built by my own hands. Used Kivy to create sliders for sleep start/end times Calculated total sleep duration (including overnight logic) Stored data with timestamps into a local SQLite DB Kept UI clean and responsive using .kv structure Repo is public here → 👉 https://github.com/bobaSloba/habit-tracker-mobile Visual graphs for sleep over time using Matplotlib A monthly calendar view with colored day blocks: 🔴 Less than 6h 🔵 6–8h 🟢 8h+ Later, I’ll build the Calories tab, then Workouts, and finally the GPS-based Running Tracker. Learning to code in public is more motivating than I expected. Every little push feels like building a new part of myself — one commit at a time. If you’re learning Python, Kivy, or just working on your habits and mental health too — let’s connect. See you in Day Three.  ( 3 min )

Desktop is trickier because neither Windows or Linux come with default, client-side mapping software. macOS, however, does come with (Apple) Maps. It would be nice if, on websites, we could create one link that had enough data in it that it could open a default app or website for people to get driving directions. In other words, not a link to Google Maps. Not a link to Apple Maps. Just enough metadata for the browser to open the mapping software of the user’s choice. First, some definitions. URL, an acronym that stands for Uniform Resource Locator, best known as web links. URLs have the following format: [scheme]://[host]/[path]?[query]#[fragment] If we take …  ( 7 min )

A new open source toolkit called ProT-Vision has just been released, enabling fast and interpretable classification of protein structures using AI. Designed by a team from EMBL and ETH Zurich, ProT-Vision leverages visual representation learning to identify structural patterns in protein folds, active sites, and domains. Converts 3D protein data into image-like grids for CNN analysis Supports PDB and AlphaFold formats with automatic preprocessing Pretrained models for SCOP and CATH classification Interactive notebooks and plugins for PyMOL and ChimeraX from protvision.io import load_structure protein = load_structure("1CRN.pdb") print("Predicted fold:", label) ProT-Vision enables protein structure researchers to annotate large datasets in seconds instead of hours. Its accuracy rivals traditional structural alignment tools, while being far more scalable. Applications include drug target classification, enzyme function prediction, and evolutionary analysis. By using CNNs on voxelized structures, the tool avoids overfitting and provides saliency maps that highlight functionally relevant regions in the protein. The toolkit is hosted on GitHub with detailed docs, Docker containers, and ready-to-use datasets. It is compatible with Linux, Windows, and macOS and requires only PyTorch and Biopython to get started.

Reactive HTML Without JavaScript Frameworks 🔥 Anthony Max ・ Jul 7 #webdev #javascript #programming #opensource  ( 2 min )

As a Senior Software Engineer, you’ve probably dealt with the challenges of microservices; service discovery, load balancing, observability, and security. Managing these concerns in a distributed system can be messy if each service has to handle them independently. Enter Service Mesh a dedicated infrastructure layer that handles service-to-service communication so you don’t have to. Think of it like traffic control for microservices: instead of every service reinventing the wheel for retries, timeouts, or encryption, the service mesh takes care of it transparently. 1. What is a Service Mesh? (The Traffic Cop Analogy) Imagine a busy city intersection: Without a traffic cop, every driver (microservice) must independently decide when to go, stop, or yield. Chaos ensues. With a traffic cop (…  ( 5 min )

In the modern web development landscape, JavaScript frameworks like Vue, and Angular dominate discussions about reactive interfaces. However, it's entirely possible to create reactive HTML without relying on these heavy frameworks. In this article, we will talk about how you can do this using this project. Well, let's start! 🏎 While JavaScript frameworks like Vue and Angular offer powerful tools, they come with significant drawbacks. One major issue is boilerplate code – developers often write repetitive setup code before implementing actual features. Frameworks also impose their own architecture, which can be overly complex for simple projects. Additionally, frequent updates may require costly migrations, making maintenance difficult over time. Another concern is performance overhe…  ( 5 min )

If you’re a developer or tech writer, chances are you’ve faced the dreaded writer’s block more than once. You have a great topic in mind, but sitting down to write feels overwhelming. Your mind goes blank, or you jump between ideas without direction, ending up frustrated and stuck. One major cause is lack of structure. When you don’t have a clear roadmap, it’s easy to get lost in the details or struggle to organize your thoughts. Without a solid outline, writing becomes a chore instead of a flow. Creating an outline before writing helps by: Breaking down your topic into manageable sections Prioritizing key points logically Making your writing focused and clear Saving time during drafting and editing But here’s the catch: building a detailed, effective outline can be time-consuming and itse…  ( 5 min )

The Problem: Content Creation is Sloooow (and Doesn’t Scale) Every content team hits the same wall: Planning keywords, structures, outlines Writing each article manually Optimizing for SEO: titles, headings, links Publishing on platforms like WordPress, Ghost, Webflow The end result? A slow-moving pipeline that can’t keep up with content demands. Teams either fall behind, stretch budgets, or risk low-quality “thin” content. Hiring freelance writers: Expensive and inconsistent output. Repurposing old content: Time-consuming and often redundant. Manual scaling: Requires massive teamwork, and still takes months to produce dozens of posts. It’s not just about output.

As developers, we love to build. Code flows, bugs are squashed, features ship. document that project, and… well, suddenly it’s time to reorganize our desk or check Reddit. Whether you're working solo or in a team, proper documentation is essential — not just for others, but for your future self. Yet writing it manually is time-consuming and often skipped in the crunch of delivery. So let’s solve this with a bit of automation — and a touch of AI. Lack of documentation causes: Slower onboarding for new team members Repeated “how does this work again?” moments Loss of knowledge when contributors leave Increased bugs and maintenance costs Yet the documentation always ends up being: Outdated Incomplete Or just… not written at all You might already be using tools like Docusaurus or MkDocs.

For years, we’ve relied on responsive design to make sure our websites and apps look great on every screen. Media queries, flexible grids, and breakpoints have been our best friends. But what if we could go one step further — and make our UIs adapt not just to screen size, but to what our users actually need in the moment? That’s where AI-powered adaptive UIs come in. And it’s not science fiction anymore — it’s already starting to happen. You’ve probably heard these terms tossed around interchangeably, but they’re not the same: Responsive UI adjusts layouts to the device — like a phone vs. a laptop. Adaptive UI adjusts layouts, content, or features based on how the user is behaving, where they are, or what they’re trying to do.

Hello Devs! 👋 I'm following the Akshay Saini DSA course, and today was all about warming up with JavaScript fundamentals. Here's a quick summary of what I learned 👇 🔰 Course Introduction “Don't just learn DSA for interviews. Understand the concepts deeply — interviews will become easy automatically.” He also suggested maintaining our own notes or copy — writing things down helps a lot in revision! 🔥 JavaScript Basics Refresher This simple line prints text to the console. The value "Hello Laxman" is a string — in JavaScript, strings are enclosed in double quotes ("") or single quotes (''). 2️⃣ Data Types String → "hello" Number → 10, 3.14 Boolean → true, false Object → { key: "value" } Array → [1, 2, 3] 2️⃣ Variable Declarations: let vs const let a = 10; → allows reassignment (a = 20 is fine) const b = 15; → does not allow reassignment (b = 20 will throw an error) We can access them like: console.log(a); // Output: 10 3️⃣ Arrays let arr = [1, true, false, [1, 2]]; Accessing values: arr[0] → 1 arr[3][0] → 1 (nested array access) Arrays store data as index-value pairs, starting from index 0. 4️⃣ Objects let person = { name: "Laxman" }; console.log(person.name); // Output: Laxman 📌 Wrap-up I’ll be sharing my progress daily. Feel free to connect or follow along if you're also on this path! Until tomorrow, happy coding! 🚀  ( 4 min )

In the last post, we talked about stack, stack trace and symbols, and how to make use of these. I've mentioned that in future i would like to focus on replacing GCC __builtin_return_address() with frame-pointer unwinding and improving symbol lookup performance with binary search. So, lets begin. Frame pointer unwinding is a method which can be used to get backtrace (iterate through stack trace). It assumes that every function has stored the frame of previously called function using frame pointer (in our case ebp register, because we're on x86 - or for example rbp on x86_64, fp (aka x29) on AArch64, etc.). This creates a linked list of frames, where each frame points to the one below it (i.e., the caller's frame). That allows us to traverse the call stack in a straightforward way — just by …  ( 4 min )

The performance of expertise is dying. What's replacing it is quieter, more powerful—and finally scalable. 🪞The Collapse of Performed Expertise Decks became sacred texts. Buzzwords became armor.

Problem Statement Given a circular integer array arr[], the task is to determine the next greater element (NGE) for each element in the array. The next greater element of an element arr[i] is the first element that is greater than arr[i] when traversing circularly. If no such element exists, return -1 for that position. Circular Property: Since the array is circular, after reaching the last element, the search continues from the beginning until we have looked at all elements once. Input: arr[] = [1, 3, 2, 4] Input: arr[] = [0, 2, 3, 1, 1] 1 ≤ arr.size() ≤ 10^5 To find the next greater element for each value in a circular array, we need to determine, for each number, the next number in traversal order that is strictly greater than it. We use a stack to keep track of the indices of element…  ( 5 min )

🔷 Java vs JavaScript: What’s the Difference? 🤔 As a developer diving into both Java and JavaScript, I often see beginners confused by their similar names. But in reality, they are two completely different technologies serving different purposes. Let me break it down: ✅ Java — A powerful, object-oriented, general-purpose language. Used for building robust backend systems, Android apps, enterprise solutions, and more. Runs on JVM, compiled, and strongly typed. “Write once, run anywhere.” ✅ JavaScript — The language of the web. Lightweight, interpreted, and primarily used for frontend web development to make websites interactive. Can also power backend (Node.js), mobile apps, and even desktop apps. Runs in browsers and is dynamically typed. ✨ Despite their names, they are not related — JavaScript was named during the Java hype in the 90s to attract attention. Both are incredibly valuable to learn depending on what you want to build — and as a Full Stack Developer, mastering both opens up even more opportunities! 💬 What’s your favorite — Java, JavaScript, or both?

Why I Built use-s-react I've always liked React's functional style, but when it comes to managing state in the application, things get complicated and whatever alternative you choose, you end up writing the detested boilerplate. useState is great for local values, but managing shared state across components? That often meant jumping to useContext, Redux, Zustand, or other more complex tools. It's not just boilerplate, if you want to use a third party library, you also end up having to learn new concepts or approaches to make use of it.

I am not understanding why this is needed, I tried to research but my efforts were unpromising. Thanks! // === Shift all characters one space to the right (after insertion) === function shiftRight(row, col) { // Flattened index of the insertion point // Shift everything from this point to the right by 1 for (let i = ROWS * COLS - 2; i >= row * COLS + col; i--) { const from = i; // Current character index const to = i + 1; // Destination index (1 cell to the right) // Convert 1D index to 2D row and column const fr = Math.floor(from / COLS); // From row const fc = from % COLS; // From col const tr = Math.floor(to / COLS); // To row const tc = to % COLS; // To col // Move character to the right grid[tr][tc] = grid[fr][fc]; } // Clear the last cell in the grid const lastIndex = ROWS * COLS - 1; // Final 1D index of the grid const lastR = Math.floor(lastIndex / COLS); // Last row const lastC = lastIndex % COLS; // Last col grid[lastR][lastC] = DASH; }  ( 3 min )

🧩 Microservices in Node.js: When They Help (and When They Hurt) “Microservices are like roommates: great in theory, chaotic in practice.” — @backend_philosopher Are Microservices, Really? Imagine if your app was a giant spaghetti monster (aka a monolith 🍝). Now imagine cutting it up into small, separately deployable meatballs — each doing one job. That’s microservices: multiple services, each running independently, communicating through APIs. In Node.js, it’s all about tiny Express servers talking to each other like gossiping teenagers on Discord. Help 1. 🧠 Your App Is Actually Big You’re running a massive e-commerce platform with inventory, payment, user management, notifications — and your current repo has 98 folders named utils.

Web UIs often look like magic compared to native apps. I used to think the web had some mythical language behind it. Turns out? C++ engine example Chrome, running CSS, JavaScript, and HTML. The elegance doesn’t come from the syntax, but from the ecosystem. Web dev moves fast because the market demands it. Here's the fun part: almost every low-level language can hook into C or C++. Golang is no different. You don’t need a miracle to build beautiful GUIs in Go. Just wire up a lightweight webview and let Go in the backend do what it does best: be fast and powerful. Here are 3 battle-tested ways to do it: Golang Wails – A production-ready webview stack with frontend templates baked in. Web UI – Spin up the user’s existing browser and inject your HTML/CSS/JS directly. Raw Webview – Like Wails, …  ( 7 min )

At some point, your project outgrows the usual patterns. It starts to split into mini-projects, not big enough for separate libraries (which are a pain to manage), but too isolated to share logic cleanly. But the real headache begins: when two or more of these mini-projects need the same behavior. Which is a full-blown object with state. The answer? Singleton structs, objects you create once and reuse across your app, with state and all. Hoist it. Literally. It’ll save you from half the complexity. I hit this exact problem while working on my agentic project. The modelservice embeds a tiny utility server as a webhook for a browser extension. Until I embedded a frontend using WebView, which also needs a server to serve static assets (because, of course, paths are hell). Project layout: mode…  ( 5 min )

So what even is MCP? MCP, short for Model Context Protocol, is a protocol designed to enable developers and applications to provide context to agents & large language models (LLMs). MCP Specification includes support for a number of different "context" primitives that can be provided to an agent, including prompts, tools, and resources, Read that, understand that, and then forget that. The primary use-case for MCP, and the only one that popular MCP clients like Cursor, Windsurf, and Claude code support, is tools. The primary use-case for MCP right now is to plug tools (and therefore new capabilities) into your agents in a low-code, low-configuration way. Here's an example of my favorite high-impact use-case for software development: Puppeteer's MCP server. By adding a simple JSON confi…  ( 10 min )

Every great hero needs the right weapon. Captain America has his shield, Aragorn wields Andúril, and David brought down Goliath with nothing but a slingshot and unshakeable faith.

Modern AI teams face a knowledge gap. Your models might be powerful, but are they speaking your organization’s language? Are they relying on your data and context, or hallucinating answers out of thin air? Let’s talk about a bold new solution: an integrated Knowledge Base for AI - something no one else in the AI evaluation or observability space offers today. Why AI Needs a Knowledge Base (Market Landscape & Challenges) The Problem: Most AI platforms today focus on metrics like accuracy, drift, and bias. These are important, but they miss a critical piece – context. Traditional observability tools (think drift monitoring, embedding visualizations, etc.) keep an eye on model performance, yet none of them ensure that your model’s outputs are grounded in your own proprietary knowledge.

Are you a legacy React developer? Have you heard of the chronicles of a once-mystical creature 👾 known as class based components in React? After spending so long exclusively in the React ecosystem — with only brief forays into Vue.js and Angular — I almost feel confined, as if under house arrest. It's as if React has become a pandemic and developers its captive patients. Attempting to leave this ecosystem — which has admittedly served me well in terms of developer satisfaction and community standards reminiscent of Golang — feels like swimming against the current of global popularity trends. Wait, let's pause for a moment… we're drifting from the topic. This isn't an angry rant about why you should abandon React and sail off to svelte land—I'll save those opinions for another day.

Writing clean React code isn't just about making things work — it’s about readability, maintainability, and scaling your components. Here’s a simple visual cheatsheet that highlights best practices for building better React components. ❌ Bad: ✅ Good: 💡 Use meaningful, descriptive prop names. ❌ Bad: {!isLoading ? : null} ✅ Good: {isLoading && } 💡 Use early returns and avoid nesting where possible. ❌ Bad: /components Button.js Card.js Modal.js ✅ Good: /components /Button index.tsx styles.module.css types.ts 💡 Organize by component, not by file type. ❌ Bad: const fetchData = async () => { const res = await fetch(...); const data = await res.json(); setState(data); }; ✅ Good: import { getUserData } from '@/services/user'; const user = await getUserData(); setUser(user); 💡 Keep logic in services or hooks. Components should be mostly UI. ❌ Bad: useEffect(() => { window.addEventListener('resize', handleResize); }, []); ✅ Good: useEffect(() => { window.addEventListener('resize', handleResize); return () => window.removeEventListener('resize', handleResize); }, []); 💡 Always clean up your effects to avoid memory leaks. Clean code in React isn’t just for you — it’s for your teammates, your future self, and the community. Refactor small, commit often, and prioritize clarity over cleverness.  ( 3 min )

In May, I published a detailed technical breakdown of a fatal, platform-level crash in AWS Lambda — a Node.js function inside a VPC making outbound HTTPS calls that would silently crash after returning a 201. No logs. No errors. No stack trace. AWS eventually reproduced it themselves. This post isn't about the bug. It's about what AWS did next. Even after AWS reproduced the crash using their own test code, their response wasn’t engineering. It was damage control: They blamed our code They revoked a previously granted $4,000 credit They silently billed our founder’s personal card They filtered technical escalations through sales They offered the credit back — this time as a settlement tied to silence And they asked our CEO, off-record, not to publish We published anyway. Culture, Not Code This isn’t a teardown of runtime behaviour. That’s already done. This is about support failure, accountability avoidance, and AWS’s cultural instinct to deflect rather than own fault. If you’re building serious workloads on Lambda: read this. Because when support fails, logs go dark, and engineering won’t speak — you are on your own. Read the full follow-up post here  ( 3 min )

Introduction As English is not my first language, this post has been carefully translated and refined from the original Japanese version I wrote, which you can find on Qiita here. When exploring tool development using Gemini CLI, I noticed that Google provides generous free usage quotas. By combining these with Claude Code, I thought we could create an MCP that complements Claude Code's missing capabilities (image generation, audio synthesis, etc.), expanding AI utilization possibilities while keeping costs low. This led to the development of CGMB. CGMB (Claude-Gemini Multimodal Bridge) CGMB is equipped with intelligence that understands user intent and automatically routes tasks to the optimal AI layer.

Why an Information Security Policy Is Crucial An Information Security Policy plays a vital role in an organization’s overall risk management and cybersecurity strategy. It provides a structured and standardized approach to identifying, mitigating, and managing the risks associated with data and information systems. By setting clear expectations and guidelines, the policy ensures that all employees, partners, and stakeholders understand their responsibilities when it comes to safeguarding sensitive information. One of the key reasons this policy is essential is that it fosters a culture of security awareness across the organization. When employees know what is expected of them and receive proper guidance, the chances of accidental data leaks, human error, or negligent behavior significant…  ( 4 min )

It Started With an Email Subject: “Congratulations! You've Just Won ₦750,000 in the Dangote Empowerment Grant!” I almost laughed when I saw it in my inbox. The email had all the usual red flags: questionable grammar, a blurry logo, and a sense of urgency that felt manufactured. It was the kind of thing most people would delete without a second thought. But I was curious. As a cybersecurity analyst based in Lagos, Nigeria, these kinds of scams were textbook. I didn’t open it to fall for it. I opened it to analyze it. Just to inspect the headers. Just to examine the phishing structure. Just to see how lazy the attacker was. The link inside looked like a Google Docs form, rebranded to look like an official grant registration portal. I clicked it from a hardened browser I use strictly for san…  ( 6 min )

"Sometimes it’s not about what you add, but what you protect." In my internship journey, I revisited a crucial lesson that every developer (especially full-stack ones) should hold dear: never trust the frontend when it comes to security. 🔍 The Problem It felt secure... until I asked myself: Answer: They might just bypass all our hard work. 🔒 The Solution: Backend Enforcement 🧰 Backend Guards and Decorators custom guards and decorators in NestJS: ts // Example: Role Guard @Injectable() export class RolesGuard implements CanActivate { canActivate(context: ExecutionContext): boolean { const request = context.switchToHttp().getRequest(); const user = request.user; const requiredRoles = this.reflector.get('roles', context.getHandler()); return requiredRoles.includes(user.role); } } // Used like this: @UseGuards(RolesGuard) @Roles('admin') This simple logic ensures that even if someone sends a forged request, they won't pass unless the role matches. 🔁 Workspace Validation A @WorkspaceMember() decorator Logic to confirm the user is part of the workspace they’re acting on AuthorizationService with reusable checks 🧪 Testing Can an admin delete a document? Can a lawyer access a case from a different workspace? (They shouldn’t) Can anyone else invite users to a workspace? 💡 Takeaways Frontend is UX. Backend is law. NestJS makes it easy to build modular, reusable security logic Good security is invisible to the user — and obvious to the developer I now have a deeper respect for backend checks and how they actually protect users ❓ Today’s Question I’d love to hear how others handle authorization at scale.

Introduction In this second part of the series, we’ll build a simple yet secure login page — entirely without a backend. Using only browser-based cryptography, local storage, and Redux, we’ll create a seamless login experience. Here’s what we’ll implement: An in-memory secret key store using Redux. Protection for the main vault page based on key presence. A login form that authorizes the user via a master password. The full project is available on GitHub. You can play with the completed app here. To securely hold the cryptographic key during a session, we use Redux to store it in memory only. This means the key disappears when the app reloads — which is exactly what we want for handling sensitive data. Here’s the vault slice: import { createSlice, type PayloadAction } from "@reduxjs/tool…  ( 6 min )

HOW To Use Props Drilling In React: Define the data in a parent component: The data that needs to be shared with a deeply nested child component is typically defined as state or a variable within a higher-level parent component. In the parent component, render the immediate child component and pass the data as a prop. jsx ## How To Use Usestate: To use the useState Hook in React for managing state within functional components, follow these steps: Import useState: Begin by importing the useState Hook from the react library at the top of your functional component file. import {useEffeact } from 'react' ; funtion My componut () { UsEffeact (() => { }) } ## how to useref in react; The useRef hook in React provides a way to create a mutable reference that persists across component renders without causing re-renders when its value changes. It is commonly used for: Accessing and interacting with DOM elements. import, {useref ,usestate} from 'react'; funtion My componunt(){ const inputRef = useRef(nall); useeffact (()=> { if (inputRef.current) { inputRef.current.focus(); } }, []); return ; }.  ( 3 min )

🎬 Why I Disappeared for 2 Days (And What's Coming Next) Okay, so I need to come clean about something. If you've been following my Medium articles and noticed I've been a bit... absent lately, there's a reason. For the past two days, I've been locked in my room like some kind of hermit, learning video editing and figuring out something that's been brewing in my mind for months.

Picture this: You're building a modern web application—maybe a collaborative document editor, a live trading dashboard, or a multiplayer game. Users expect instant updates, real-time notifications, and seamless interactions. But how do you choose the right technology to deliver that experience? As full stack developers, we have three main approaches for real-time communication: traditional polling, Server-Sent Events (SSE), and WebSockets. Each has its strengths, trade-offs, and ideal use cases. Let's dive deep into when and why you'd choose each approach. Before we compare these protocols, let's establish the foundation. Traditional web communication follows a request-response model: the client asks, the server responds. But real-time applications need the server to push data to clients p…  ( 8 min )

After years of inactivity, I decided it was time for a complete overhaul of my personal portfolio. What started as a simple "let me fix this one animation" turned into a week-long intensive refactoring session that transformed the entire codebase. My original portfolio stopped working because of many deprecated dependencies. The animation system was monolithic, testing was sparse, and adding new features felt like walking through a minefield. The biggest change was moving from a single, monolithic animation controller to a modular scene-based system. Each section of my journey (freelance → company → ASOS) now has its own self-contained scene with dedicated animations. // Before: One massive animation controller const animateEverything = (progress) => { // 500+ lines of mixed concerns } …  ( 5 min )

From Web to ML Research Engineer: Day 5 of 60 Today was a breakthrough day. After four days of wrestling with linear algebra fundamentals, I finally tackled the mathematical machinery that makes modern AI possible: matrix calculus and automatic differentiation. If you've ever wondered how neural networks actually compute gradients for millions of parameters, or why PyTorch's loss.backward() is pure magic, this post is for you. It hit me around hour 6 today: automatic differentiation isn't just a neat programming trick—it's the mathematical foundation that makes training GPT-4 computationally feasible.

When we think of calling something in Python, the first thing that comes to mind is usually a function. But Python gives us the power to go a step further: objects can behave like functions if they implement a special method called __call__. This concept might seem a bit strange at first, but once you understand how it works, you’ll find it incredibly useful, especially for building clean, modular backend systems. In this blog post, we’ll dive deep into the __call__ method. We'll explore: What __call__ really does under the hood Why and when you should use it The potential pitfalls to watch out for Realistic backend examples Let’s get started. __call__ Method? In Python, every function is an object. And just like functions, any object that implements the __call__ method can be used with …  ( 5 min )

After six decades of debate, a new Science paper used RNA‐sequencing on hippocampi from teens to 78-year-olds and pinpointed the elusive neural precursor cells and immature neurons—finally proving adult human brains keep churning out new neurons. This confirmation of adult neurogenesis could shake up our approach to memory, mood disorders, Alzheimer’s and epilepsy—and now the fun part begins: figuring out exactly what these rookie neurons do for brain function.  ( 3 min )

markdown Crunchyroll quietly tested out ChatGPT-generated subtitles on its new anime, Necronomico and the Cosmic Horror Show—and oof, did it backfire. Viewers spotted lines full of typos (think “Is gameorver. if you fall, you are out”) and even bits that literally start with “ChatGPT said.” All signs point to zero human editing, despite the streamer’s promise not to lean on AI for its programming. This mess flies in the face of Crunchyroll president Rahul Purini’s vow to keep AI out of the creative process and protect voice-actor jobs. Sure, the company is keen on AI for recommendations and discovery, but this fiasco shows why real translators and localizers still matter—rushed, unedited AI churn doesn’t just break immersion, it undercuts authenticity.  ( 3 min )

Julian McMahon, the Aussie actor who lit up screens as Dr. Christian Troy on Nip/Tuck and the Human Torch in the early-2000s Fantastic Four movies, died July 2 in Clearwater, Florida after a private battle with cancer.

After completing the basics of frontend development, I wanted to challenge myself with a project that tested both my UI skills and my understanding of API integration. Inspired by Netflix’s clean interface and movie layout, I built this Netflix Clone as a solo React project — and it’s now live on Netlify! Netttflix is a Netflix-inspired movie browsing app built with React, using the TMDB (The Movie Database) API to fetch real-time movie data. The app showcases trending movies, categories like “Top Rated” and “Now Playing,” and allows users to explore titles with smooth horizontal scrolling. Working on this clone helped me get hands-on experience with: One of the tricky parts was handling API calls efficiently while avoiding code repetition. Another challenge was implementing responsive horizontal scroll behavior across screen sizes — especially making it work smoothly on both desktop and mobile. This Netflix Clone was a super fun project that helped me bring together everything I’ve learned so far in React. It gave me confidence in building clean UIs, integrating APIs, and deploying projects professionally using Netlify. 👉 Live App: https://netttflix.netlify.app GitHub Repo: https://github.com/abdulhaseebshah/netflix-clone If you check it out, I’d love your feedback.

Alexander the Great conquered half the known world by the age of 30. But it wasn’t just him. It was his army, loyal generals like Hephaestion, fearless soldiers, brilliant minds, and mentors like Aristotle who shaped him before he even picked up a sword. When he reached the edges of India, even Alexander had to stop. His army was exhausted. They refused to move forward. And that’s when it hit me… Even the greatest can’t walk forever alone. Reminder to myself: I can push hard. I can work late. I can carry the weight alone, for a while. But no matter how far I go, time is limited, energy burns out, and the silence gets heavier. A vision, no matter how clear, needs voices behind it. A mission, no matter how big, needs hands around it. So I remind myself, don’t wait to break. Build your army while you climb. Surround yourself with people who believe, challenge, and carry pieces of this dream. Because the truth is… “No man walks on his own story for too long. Even legends need footsteps beside theirs.” — Rengo Every great story is written with many hands.  ( 3 min )

I’ve come to learn something important about Proof of Concepts (POC)—a lesson I want to write down so I don’t forget. When working on ambitious ideas like combining NFTs with AI, I used to think that a POC was just the smallest version of the idea. That if I could build anything at all, no matter how simple, I had done enough. But that's not how it works. Not really. A POC is not about building the smallest thing possible. It's about building the smallest thing that matters. There’s a difference. A Misstep I Took At one point, I was excited about the idea of using AI to generate art and minting it as NFTs. I thought, "Let me just generate some AI art, mint it as NFTs, and call it my POC." But here’s where I was wrong: just generating AI art and turning it into NFTs didn't prove anything useful. It wasn’t hard. It didn’t teach me anything about how my idea would work at scale, or whether it even had value. It was a shallow demo, not a real POC. What I needed to test was "the part that makes my idea unique." Maybe it was the ability of the AI to customize art based on real-time inputs. Or maybe it was about creating rarity through AI learning from trends. That’s what my POC should have focused on. What I Realized A good POC asks: "Can this concept work the way I think it will?" It’s not: "Can I build anything at all that looks kind of like this?" The smallest concept is often irrelevant if it doesn’t reflect what you actually need to validate. So now, I approach POCs differently. I ask: What is the minimum valuable learning I need from this build? If I can answer that honestly, I can build a POC that actually moves me forward. Final Reminder to Myself Just because something is “built” doesn’t mean it’s useful. A POC is not a checkbox or a toy version of your big idea. It's a filter. It helps you know if your idea can stand on its own, even when stripped down. From now on, I’ll remember: A good POC is not the smallest thing I can make. Stay focused, test the right thing, and build smarter.  ( 4 min )

Two concepts are central to responsible AI development: alignment and oversight. Alignm…  ( 7 min )

Content is king — but consistent visibility is what builds brand authority. Publishing high-quality articles once isn’t enough. You need to repurpose and distribute content across multiple platforms — fast, accurately, and SEO-safe. That’s exactly why we built a fully automated content distribution system using Make, combined with APIs from Dev.to, Medium, Hashnode, and others. Even with great content, distribution is a bottleneck: Manually uploading articles to multiple platforms Copy-pasting tags, excerpts, metadata Risking duplicate content without canonical URLs Delayed publishing means missed reach opportunities All that effort can lead to inconsistency, content decay, and lost SEO value. We used Make.com (formerly Integromat) to architect a modular content workflow that publishes …  ( 4 min )

Look, I'll be honest with you. Six months ago, I was that guy rolling my eyes at Foundry enthusiasts on Twitter. "Another Rust fanboy trying to reinvent the wheel," I thought. My Hardhat setup was working just fine, thank you very much. I had my plugins, my familiar JavaScript tests, and years of muscle memory built up around the ecosystem. Then I got a consulting gig that changed everything. A DeFi protocol team hired me to audit their testing infrastructure across 50 different protocols in their ecosystem. Some used Hardhat, some used Foundry, and a few brave souls were using both.

Digital certificates form the backbone of modern internet security, enabling everything from secure web browsing to email encryption. At the heart of this system lies the concept of a "chain of trust" based on X.500 digital certificates. However, while this system appears robust on paper, real-world incidents reveal significant vulnerabilities and power imbalances that affect global internet security. X.500 digital certificates are based on the ITU-T X.509 standard, which defines the format for public key certificates. These certificates bind a public key to an identity (such as a person, organization, or device) and are digitally signed by a Certificate Authority to verify their authenticity. Each X.509 certificate contains: Subject information: The entity being certified Public key: The …  ( 10 min )

AI can no longer operate in the shadows. As machine learning (ML) becomes embedded in decisions that shape drilling strategies, supply chain flows, and asset performance, a critical question rises to the surface: Can we trust the model? Enterprise AI is moving fast, but oversight must keep pace. Scaling ML systems requires more than innovation; it demands visibility, accountability, and regulatory alignment. Databricks Unity Catalog is emerging as a critical platform for ML governance, enabling traceable model development, integrated risk tracking, and unified data compliance. Why governance can’t be optional Unity Catalog in action Case in point: AI oversight in upstream operations At Traxccel, we led the implementation of Unity Catalog to establish end-to-end lineage across geospatial data pipelines, sensor inputs, and predictive maintenance models. Within months, the majority of operational models were fully documented, including lineage and access control metadata. This improved model explainability and enabled proactive detection of data drift related to seasonal input variations. Governance was embedded directly into CI/CD workflows, supporting compliance without slowing innovation. Building for trust at scale Learn more: https://www.traxccel.com/axlinsights  ( 4 min )

In this article, we’ll explore various methods of including external JavaScript module files into your main or controller files. With ES6, we’ve got an excellent feature: the ability to export and import modules. This makes your code more organized, readable, and modular. Let’s dive into the topic. In a JS file, when you write multiple functions and want to use them in another file, you can use the keyword export. If you want to export more than one function, you can do it like this: export { function1, function2, function3 } Example: const sub = (a, b) => { return a - b; } const add = (a, b) => { return a + b; } export { sub, add }; Now, if you have only one function to export, there’s a special way to do that — using export default const multiply = (a, b) => { return a * b; } …  ( 4 min )

Okay, not gonna lie — if you’re scrolling right now, probably thinking about making some extra cash, and you’re not using ChatGPT to do it? You might be missing out big time. Seriously. This isn't some pumped-up "get rich quick" pitch. It's just the raw truth: AI has genuinely made it ridiculously easy to kickstart side hustles that can actually put money in your pocket. You don't need a fancy degree or years of experience. You don't need to be a master wordsmith or a coding genius. If you can type a sentence and ask ChatGPT a question, you've got the basic tool.

Hey Dev.to community! 👋 I'm excited (and a bit nervous) to share the first entry in my journey of building something new and rebuilding myself along the way. Back in 2013, I got into crypto early. Through some well-timed investments — including SHIB and a few other early movers — I did quite well. For a while, I was one of those "lucky ones" riding the hype wave. But as we all know, luck isn’t a business model. Through a mix of harsh taxation, bad reinvestments, and plain overconfidence, I ended up losing most of what I gained. A classic rollercoaster story. And you know what? I don’t regret it. That chapter taught me that real value doesn’t come from chasing markets — it comes from building things that last. I’ve been a developer since 2010, working in a range of tech companies — includi…  ( 4 min )

Vue is fast, elegant, and powerful. But if you're building a public-facing site — especially one that needs to rank on Google — there’s one critical decision you need to get right: Should you render on the client (SPA) or server (SSR)? Many developers love Vue because it lets you build dynamic, component-driven apps quickly. But the way your Vue app renders can make or break your visibility in search engines. By default, Vue apps are SPAs — meaning everything renders on the client side, after the browser downloads your JavaScript. This is great for speed and interactivity once loaded, but it poses a serious issue for SEO: Googlebot often doesn’t wait for your app to finish rendering Meta tags, Open Graph data, and structured data might not be seen Rich snippets may not show in SERPs Pag…  ( 5 min )

So here's a quick post on something that cost me a good bit of time. I had launched an EC2 instance from a custom AMI, and right after the boot it started failing EC2 instance reachability checks. The instance was running, but I couldn't SSH into it. So I checked system logs via EC2 console and found this: network: Bringing up interface ens5: ERROR : [/etc/sysconfig/network-script/ifup-eth] Device ens5 has different MAC address than expected, ignoring what actually happened? I had created an AMI from a running instance without cloud-init installed. So the image had the original MAC address hardcoded in /etc/sysconfig/network-scripts/ifcfg-ens5. When I launched a new ec2 instance from this AMI, AWS assigned a new MAC address to the network interface but the OS was still looking at the old one. It was a classic mismatch and therefore network failed to initialise, and so did the reachability check. How I debugged it? Since I couldn't SSH into the instance, here's what i did: Stopped the instance, detached it's root volume and attached it another working instance in same availability zone as a secondary volume(e.g., /dev/xvdf). Mounted the volume to a temporary directory: sudo mkdir /mnt/temp sudo mount /dev/xvdf1 /mnt/temp Edit the network config file and delete the line with HWADDR compeletely. vi /mnt/temp/etc/sysconfig/ Unmounted the volume, detached it and attached back to original instance as root volume and started it. Hurray! I was able to connect succeessfully How to prevent this from happening? Install cloud-init before creating your custom AMI  ( 3 min )

In the world of Kubernetes, managing and customizing configurations across multiple environments or instances can be both crucial and complex.

Utility-first frameworks encourage the use of small, composable classes directly in your HTML to apply styling. Rather than writing custom CSS for every element, developers use predefined utility classes that do one job well—like adding padding, changing text color, or aligning elements. This might seem counterintuitive at first, especially if you’re used to writing semantic CSS. However, once you experience how efficient and maintainable it becomes, it’s hard to go back. Utility-first design prioritizes function over form when naming and organizing styles. By doing so, you get benefits such as: Rapid prototyping – You can build UIs directly in your markup without switching between HTML and CSS. Smaller CSS footprint – By using predefined classes and eliminating the need for custom styles,…  ( 4 min )

This is a submission for the Runner H "AI Agent Prompting" Challenge Ever find yourself wondering "What's the top anime this season I shouldn’t miss?" Yeah, me too. So I created a Runner H workflow that asks an AI agent to fetch and organize the best anime airing this season (Summer 2025) based on real ratings from sites like MyAnimeList, AniList, and Crunchyroll. This prompt gets the hottest titles, along with posters, synopses, genres, scores, streaming platforms, and even a short reason why each show is getting all the hype. Then the agent neatly bundles all that glorious info into a beautiful PDF report – complete with cover, TOC, and summary. Basically: weebs get a cheat sheet for what to binge next. I crafted a clean and simple natural language prompt, which Runner H sends to the AI agent. The agent: Crawls popular anime sites and aggregates the top-rated airing series Organizes them by genre and age group Fetches key info like posters, synopses, and streaming availability Generates a polished PDF report (with page numbers and all 👀) Here's the actual prompt: Give me a list of the best new anime this season (Summer 2025) based on ratings from sites like MyAnimeList, AniList, and Crunchyroll. For each anime, include: Title Poster Synopsis Genres Score and where it came from Why it’s popular or highly rated Where to watch (streaming platform) Group them by genre and age group (teens, adults, all ages if available). Limit the list to 10–15 titles max. Then create a clean, nice-looking PDF report with a cover page, table of contents, and summary at the end. Anime fans who want to know what’s worth watching this season Content creators writing seasonal reviews or doing anime tier lists Streamers looking for hot new shows to react to Community mod teams posting seasonal recommendations in Discord or forums No more hopping between 3+ sites to figure out what’s trending. Just run this prompt and get a curated PDF to share, post, or read while sipping matcha under your kotatsu. follow my social media Twitter  ( 4 min )

The simple fact is Power Automate and other automation tools are not free, so the expectation is for a Return on Investment (ROI), but that (until now) has not been easy to calculate in Power Automate.

We’ve all been there. A tight deadline. A bug that’s blocking a demo. A client breathing down your neck. So, we do what feels efficient at the moment — a quick fix. But weeks later, that “just-for-now” tweak has morphed into a monster that no one wants to touch. What started as a shortcut becomes technical debt that silently drains time, money, and sanity. Let’s break down why these quick fixes can haunt your codebase and how you can avoid that future pain. Quick fixes are fast, often superficial solutions to problems that arise during development. They work — for now — but are rarely robust, scalable, or clean. Examples: Hardcoding values instead of using config files Disabling validations to “make it work” Skipping error handling Copy-pasting code instead of refactoring Here’s a classic…  ( 5 min )

Note: I'm always talking about server components here. Sequence of await usages Wait until the previous fetch is complete. Promise.all() When one of the fetches is slower than the others, Data fetching and rendering happen only when building the application (during deployment) revalidating data The cached data is served whenever a user visits the application. Pros: Pre-rendered content can be cached when deploying, resulting in faster websites. The server doesn't have to send the content because it's already cached, resulting in reduced server load.

If I had a dollar for every founder who said, “I’m excited to announce…” like they were narrating a funeral (of someone they never met), I’d have enough to fund my own startup, buy a failed one off Craigslist, and still have cash for launch party confetti. Yet again, I watch a video of two dudes too tired to put on a fake American smile. One drones a lullaby of buzzwords. The other one nods like a human metronome on 1-second intervals. Sure, it’s your 14th take. Your cofounder’s holding the iPhone. Their hands are cramping. The pizza’s cold. Everyone wants to go home. One of you never wanted to be here in the first place. But if you can’t fake excitement (or at least hide disappointment) for your own launch, why should anyone else feel it for you? I imagine it’s hard to cultivate excitemen…  ( 4 min )

When our team imported about 90,000 historical records into our production database, we discovered that our Entity Framework Core queries, which had performed well with smaller datasets, suddenly began timing out. This case study examines the performance bottlenecks we encountered and the optimization techniques that resolved them. Our application had been running smoothly with a modest dataset of about 1,000 records. The dashboard loaded consistently in under 2 seconds, monitoring showed healthy performance metrics, and users were satisfied with the response times. The data migration was intended to be routine—importing historical records from a legacy system to provide users with years of valuable information. However, when users began accessing the system, we encountered significant per…  ( 6 min )

Hey! I’m working on a Java project called JNova — it's a modular networking framework built from scratch with a focus on reactive programming, custom protocol handling, and support for different transport layers like TCP, UDP, and Kafka. The idea is to create something flexible and lightweight — kind of like Netty or Spring WebFlux, but without the boilerplate or heavy abstractions. I'm aiming for something that feels modern and hackable, especially for backend, server, and terminal-based tools. Some of what’s already in progress: A TCP server core built around Project Reactor A unified request/response system that works across multiple protocols Annotation-based request handler registry with type dispatching + injection Plans for a RequestBus to route messages across all transport layers Simple demo apps (chat system, terminal UI, etc.) I’m looking for people interested in: Java networking Reactive programming (Reactor/Flux/Mono) Building low-level tools and clean APIs Protocol design or transport layer stuff (UDP, Kafka, etc.) Making cool backend/dev tools with it If you’re curious or want to help, I’d love to talk.

Sudoku-Like Puzzle Rules General Puzzle Structure The puzzle has 40 hexagonal cells arranged in a trapezoidal layout: Rows of 6, 7, 8, 9, and 10 cells (from top to bottom). Each cell can contain an integer from 1 to 10. All values must be placed such that: Each integer (1-10) appears exactly 4 times across the entire grid. Block Constraints The grid is divided into 8 blocks (each with 5 cell indices). For each block: No duplicate values. Each block must contain at least one prime number (2, 3, 5, or 7). Every prime in the block must be adjacent (a common edge) to an even number. Exception: value 2 is exempt from this requirement if it is in one of the two special blocks (see below). The sum of the values in each block must be unique (no two blocks can have the same total). *Special Block Rule: {2, 3, 5, 7, X} * Exactly two blocks must contain the set {2, 3, 5, 7, X}. In one of these blocks, X must be odd; in the other, X must be even. In these blocks: The 2 is exempt from needing to be adjacent to an even number. Adjacency Rule Two cells are adjacent if they have a common edge. For every prime value (except 2 in special blocks), there must be in the same block an adjacent cell that holds an even value. Alignment Rule There is an alignment mapping across the 40 cells. Cells that are "aligned" (e.g., in the same visual row, column, or diagonal) must not contain duplicate values. Note: Each cell usually has 6 (not 3) alignments, 3 along the edges and 3 along the vertices. No Duplicate Values No repeated values within: Any block, Any alignment group, The global digit distribution (each digit used exactly 4 times) The puzzle has a verified solution.  ( 3 min )

Over the past several months, I’ve been collaborating with AI coding assistants — not just to build software, but to explore a deeper question: “What kind of environment would an AI prefer to work in?” What emerged through daily interaction, debugging, and refinement feels more like a foundational architecture than just another framework — a pattern that helps AI coders stay coherent, contextual, and efficient. We’re calling it Constellation Architecture. This hasn’t been the result of working with just one AI model. I’ve tested and refined the architecture with multiple AI coding assistants across different sessions and platforms. While each has its nuances, they consistently recognize and affirm the value of this environment. Their agreement — both in behavior and direct feedback — sugge…  ( 4 min )

Yesterday, I attended an interview at SCYO, which is located in Perungudi, Chennai. At first, it was a bit difficult for me to reach the company because I didn’t know the exact route. I used Google Maps to find the way and finally reached SCYO. But it was totally worth it — the workplace was really impressive, and I liked the environment a lot. I even felt that if I get placed there, I would never want to leave the company. The HR was also very friendly and kind, which made me feel comfortable. The interview had 5 rounds in total: Aptitude Round – This round tested our logical thinking and basic problem-solving skills. HR Round – A face-to-face discussion where they asked about my personal details, strengths, and background. Typing Test – In this round, they checked our typing speed and accuracy. Grammar Test – This included basic English grammar questions to assess our language skills. Listening Test – In this round, they tested our listening ability with audio clips and related questions. Each round was unique and helped me understand what companies look for in candidates. It was a helpful experience, and I feel more confident now for future interviews.  ( 3 min )

I recently finished the Introduction to AWS Security course by Cybr. The course is part of the platform's Blue Team Learning Path This was a great course that offers great content highlighting the key features of security in AWS. The course has over 100 lessons covering the following topics: 🚧 Infrastructure Security The course contains several labs, graphical cheat sheets with detail explanations, sandbox author-hosted labs and demo videos giving details walk-throughs of services and implementations. There is a good blend of theory and practical/hands on material. If that's not all, you get nearly six credit hours for completing the course! Since this is introduction course, the author is careful to give sufficient but not overly detailed information via concise digestible videos covering the important aspects. Overall, this is course packs in some great information and the author's teaching style is solid. As a security engineer holding several AWS certifications, this course is a great buy.

As a developer, I constantly jump between websites like Google Translate, YouTube, GitHub, and countless others. - Open the site - Wait for it to load - Type in what I want It’s not terrible — but it’s two steps every single time. I started wondering: “What if I could skip the site loading part and just search instantly, like typing commands in a terminal?” That’s how TypeGo was born. What is TypeGo? Just type a shortcut command like: gt hello world …and it instantly searches "hello world" on Google Translate. Or: yt lofi chill …and you’re on YouTube, watching chill beats in seconds. Key Features Custom search engines: Add any site you want — Google, Figma, Stack Overflow, even your company’s internal tools. Command shortcuts: Define your own keywords (gt, gh, map, so, etc.) One step navigation: No need to open + search — it does both at once. Search bookmarks & history: bm and hs commands let you query your local data. No data collection: Everything runs locally. Nothing is tracked or stored externally Why build it? But in browsers, there wasn’t a simple way to jump and search any site with custom logic, unless I bookmarked or memorized URLs. So I built this tool to speed up my daily routine. How to Use Chrome Web Store Type as in the address bar → hit Tab or Space Enter your command (e.g. gt hello) Boom, you're there. You can customize all engines & shortcuts in the settings page.  ( 3 min )

Project Background I'm a beginner in AI application development. In the past, I've been focused on traditional frontend, backend, and toolchain development, with very limited knowledge about AI. Recently, I've been working on a toolchain project and writing documentation for it. Suddenly, an idea occurred to me - I could use the MCP protocol to tell AI about the project details and let it help me write code. Let's get started! After discussing with GPT, I decided to adopt the following technology stack: Backend Framework: FastAPI + Python - Chose FastAPI for its async capabilities and automatic API documentation generation Vector Database: ChromaDB (with memory fallback) - Supports persistent storage while providing memory mode for development and testing Embedding Model: Sentence Transf…  ( 5 min )

Hey algorithm navigators! 🧭 Today, we’re diving into a classic greedy scheduling problem — Max Number of Events That Can Be Attended. This challenge teaches us how to think about priority queues (aka heaps) and time-based planning. If you've ever tried to squeeze multiple meetings into a day without overlaps, you'll feel right at home with this problem. Let’s dive in! 💼 You’re given a list of events, each with a startDay and endDay. You can attend only one event per day, but you can pick any day within an event's time window. Return the maximum number of events you can attend. We sort all events by their start time. Then, day-by-day, we add events that become available on that day to a min-heap based on end day. On each day, we remove from the heap any events that have already expired. W…  ( 5 min )

TL;DR: Shadcn registries let you install UI components fast, but they can also include dev dependencies, overwrite config files, and silently inject malicious code into your project. So the other day, I was digging through the shadcn/ui registry documentation. I was exploring how the registry system works. It's a cool idea: you can define a list of components, and it installs everything you need... Dependencies, files, even configuration files etc. But then I noticed something that gave me chills. A registry.json file can have this: { "$schema": "https://ui.shadcn.com/schema/registry-item.json", "name": "component1", "type": "registry:ui", "title": "A simple component", "devDependencies": [ "vite-plugin-run" ], <----- THIS LINE ... } That seems harmless, right?

As a junior student learning web development, routing systems have always been one of the most complex parts for me. Traditional framework routing configurations often require lots of boilerplate code and lack type safety. When I encountered this Rust framework's routing system, I was deeply impressed by its simplicity and powerful functionality. Project Information Hyperlane Framework: GitHub Repository Author Contact: root@ltpp.vip Documentation: Official Docs This framework's routing system design philosophy is "convention over configuration." Through attribute macros and the type system, it makes route definitions both concise and type-safe. use hyperlane::*; use hyperlane_macros::*; // Basic route definition #[get] async fn home_page(ctx: Context) { ctx.set_response_status_code(2…  ( 6 min )

After getting comfortable using Spacelift to automate my AWS infrastructure with Terraform, I wanted to push myself a bit further, so I decided to dig into something that often gets overlooked: Policies. In real-world organizations, you rarely have total freedom to spin up any resource you want, any way you want. Teams need guardrails, ways to make sure people stick to the right instance types, permissions, regions, or cost limits, resources, etc. That’s where Spacelift’s policy engine comes in. And honestly? I must say, i struggled with it a lot, as part of my failure journey, but it paid off in a very satisfying way. It’s pretty interesting once you get your hands dirty. Before we dive in deep, let me drop an architectural diagram, hopefully you would get the concept ahead (like a spoile…  ( 6 min )

Are You Still Planning Trips the Old Way? Here’s a fun (or maybe not-so-fun) stat for you: the average traveler spends over 10 hours planning a single trip. Ten. Just let that sink in for a moment. That’s basically a whole workday spent bouncing between flight sites, hotel reviews, Pinterest boards, and Google Map rabbit holes. Sound familiar? Honestly, I’ve been there. Picture this: a couch full of half-packed bags, 14 tabs open on my browser, a spreadsheet that looked more like a crime board, and a growing sense that maybe I should’ve just taken a staycation instead. For a long time, I thought this was just how travel worked—you hustle ahead of time to get that perfect, Instagrammable experience. But then I discovered AI travel tools, and wow. Total game-changer.
